    Notes: Summary We have produced a small library of colonic mucosa and colorectal carcinoma reactive monoclonal antibodies (MoAbs) by immunizations with extracts of human colon cancer tissue and a human colon cancer cell line. Hybridoma supernatants were tested on (normal and neoplastic) human tissues by immunoperoxidase methods to evaluate organ or tissue specificity. Initial biochemical characterization of the target antigens was performed by gelpermeation chromatography, Western blotting and competition assays. Based upon the immunoreactivity patterns and the characteristics of the antigen four groups of MoAbs could be distinguished. The first group concerns the antibodies PAR-LAM 3, 9 and 10. These antibodies react with an 87 kDa protein moiety in high molecular weight (2–5×106 Da) glycoproteins. In intestinal and colon mucosa these antibodies showed diffuse binding with goblet cells. In colon carcinoma decreased reactivity with these MoAbs was found. The second group consists of antibodies PARLAM 8, 12 and 13. These antibodies react with large (〉5×106 Da) glycoproteins, most likely with carbohydrate epitopes. By immunohistochemistry in normal colon mucosa the antibodies all show granular supranuclear reactivity with goblet cells. These antibodies show increased reactivity with colon adenomas and adenocarcinomas. A third group is formed by PARLAM 2, which also reacts with a large (〉5×106 Da) glycoprotein, showing a granular distribution in goblet cells. In colon carcinomas more extensive expression is found than in normal colonic mucosa. Finally, the fourth group consists of PARLAM 11, which also reacts with a large (〉5×106 Da) glycoprotein, located in the brush border of colonic columnar cells. These antibodies might be useful tools for the analysis of the expression of mucin related glycoproteins in normal, preneoplastic and neoplastic colon mucosa.

    Description / Table of Contents: NaM2OH(SO3)2 · 1 H2O with M = Mg, Mn, Fe, Co, Ni, and Zn. A New Class of Basic SulfitesHitherto unknown hydroxide sulfites of the type NaM2OH(SO3)2 · 1 H2O with M = Mg, Mn, Fe, Co, Ni, and Zn have been obtained by crystallization from aqueous sulfite solutions containing Na+ and M2+ ions. Crystal structure, IR and Raman data, and the results of thermoanalytical studies are reported and discussed. The hydroxide sulfites show a strongly anisotropic thermal expansion due to the layer structure and exhibit an unusually high thermal stability compared to other solid hydrates. The magnesium compound, for example, decomposes at 355°C. The crystal data of the triclinic compounds see “Inhaltsübersicht”.
    Notes: Durch Kristallisation aus natriumhaltigen wässerigen Sulfitlösungen wurden bisher nicht bekannte Hydroxidsulfite des Typs NaM2OH(SO3)2 · 1 H2O mit M = Mg, Mn, Fe, Co, Ni und Zn erhalten. Die Kristallstruktur, die IR- und Ramanspektren sowie das Ergebnis thermoanalytischer Untersuchungen werden mitgeteilt und diskutiert. Die Verbindungen zeigen aufgrund ihrer Schichtenstruktur eine stark anisotrope thermische Ausdehnung. Sie besitzen eine für Hydrate ungewöhnlich große thermische Stabilität. Die Magnesiumverbindung zersetzt sich z. B. erst oberhalb von 355°C. Die Verbindungen des Typs NaM2OH(SO3)2 · 1 H2O kristallisieren triklin (P1, Z = 2) mit folgenden Gitterdaten: M = Mg: a = 890,5(1), b = 784,5(1), c = 631,5(1) pm, α = 113,28(2)°, β = 110,41(1)°, γ = 98,00(2)°, M = Mn: a = 907,6(1), b = 795,7(1), c = 648,7(1) pm, α = 112,71(1)°, β = 109,34(1)°, γ = 99,23(1)°, M = Fe: a = 898,8(1), b = 789,0(1), c = 634,8(1) pm, α = 112,06(1)°, β = 109,59(1)°, γ = 99,76(1)°, M = Co: a = 888,0(1), b = 783,7(1), c = 631,6(1) pm, α = 112,61(1)°, β = 109,85(1)°, γ = 98,93(1)°, M = Ni: a = 878,4(2), b = 777,0(3), c = 626,3(1) pm, α = 112,54(2)°, β = 109,84(2)°, γ = 99,47(3)°, M = Zn: a = 887,4(1), b = 785,2(1), c = 629,9(1) pm, α = 112,27(1)°, β = 109,67(1)° und γ = 99,66(1)°.

    Description / Table of Contents: Neutron Diffraction Studies of SrBr2 · H2O and SrI2 · H2O, Symmetrically and Asymmetrically Bonded Water MoleculesSingle crystal neutron diffraction studies were performed on the isostructural (space group Pnma) SrBr2 · H2O and SrI2 · H2O. Lengths and structure of the hydrogen bonds are correlated with Raman and IR spectroscopic data. The bifurcated and trifurcated H-bonds present are altogether significantly stronger than linear ones with similar H…Br and H…I distances, respectively. In the case of SrI2 · H2O, the H-bonds of the two hydrogen atoms of the water molecules exhibit equal strength (symmetric water molecule) as shown by the respective OH vibrational energies despite the different H…I distances. The water molecule of SrBr2 · H2O is asymmetrically bonded (different strength of the H-bonds).
    Notes: An den isotypen Hydraten SrBr2 · H2O und SrI2 · H2O (Raumgruppe Pnma) wurden Einkristallneutronenbeugungsmessungen vorgenommen. Die Bindungslängen sowie die Anordnung der verzweigten Wasserstoffbrücken werden mit Raman- und IR-spektroskopischen Daten korreliert. Die zwei- bzw. dreifach verzweigten Wasserstoffbrücken sind insgesamt signifikant stärker als gleich lange lineare Brücken zu Br--und I--Ionen. Die von den beiden Wasserstoffatomen des SrI2 · H2O gebildeten H-Brücken sind, wie die entsprechenden OH-Schwingungsfrequenzen zeigen, trotz der unterschiedlichen H…I-Abstände gleich stark (H2O symmetrisch). Das Kristallwassermolekül des SrBr2 · H2O ist asymmetrisch gebunden (unterschiedlich starke H-Brücken).

    Description / Table of Contents: Crystal Structure, F.I.R., and Raman Spectra of GaCrSe3The crystal structure of GaCrSe3 oP20 was determined by single crystal X-ray methods (final R = 1.6% for 949 observed reflections, I 〉 2σI). GaCrSe3 crystallizes in the orthorhombic space group Pnma with Z = 4 (CuTaS3 type) and a = 1011.82(7), b = 373.45(3), and c = 1239.2(1) pm. The structure is built up on rectangular columns in [010] of edge shared GaSe4 tetrahedra and CrSe6 octahedra of the sequence (GaSe4)(CrSe6)2(GaSe4) in [101] and [101], respectively, which are connected via the corners in such a manner that channels in [010] of trigonal prismatic cavities are formed. The single crystals were grown by vapour phase transport method using I2 as transporting agent. The f.i.r. and Raman spectra of GaCrSe3 as well as a group theoretical treatment of the phonon modes are reported. In the ternary system Ga2Se3-Cr2Se3, monoclinic Ga1,3Cr0,7Se3 and hexagonal CrGa1,66Se4 (FeGaS4-type) have been established additionally to the orthorhombic GaCrSe3.
    Notes: Die Kristallstruktur der bisher nicht beschriebenen Verbindung GaCrSe3oP20 wurde anhand von Einkristalldaten bestimmt (R = 1,6% für 949 beobachtete (I 〉 2σI) Reflexe). GaCrSe3 kristallisiert in der orthorhombischen Raumgruppe Pnma mit Z = 4 (CuTaS3-Typ) sowie a = 1011,82(7), b = 373,45(3) und c = 1239,2(1) pm. Der Struktur liegen rechteckige Säulen in [010] aus kantenverknüpften CrSe6-Oktaedern und GaSe4-Tetraedern der Folge (GaSe4)(CrSe6)2(GaSe4) in [101] bzw. [101] zugrunde, die über die Ecken der Oktaeder- und Tetraederbaueinheiten so verknüpft sind, daß in [010] angeordnete Kanäle mit trigonal-prismatischen Lücken gebildet werden. Die Darstellung von Einkristallen des GaCrSe3 erfolgte durch Gasphasen-transport mit Iod. Das FIR- und Ramanspektrum des GaCrSe3 sowie die Schwingungsabzählung der Gitterschwingungen dieses Strukturtyps werden mitgeteilt. Neben dem orthorhombischen GaCrSe3 existieren im System Ga2Se3-Cr2Se3 monoklines Ga1,3Cr0,7Se3 und hexagonales CrGa1,66Se4 (FeGa2S4-Typ).

    Description / Table of Contents: On Hydrates of the Type MX2 · 1 H2O with M = Sr, Ba and X = Cl, Br, I. Crystal Structures of Strontium Chloride Monohydrate, SrCl2 · 1 H2O, and Strontium Bromide Monohydrate, SrBr2 · 1 H2OThe structures of SrCl2 · 1 H2O, orthorhombic, Pnma, a = 1088.1(1), b = 416.2(1), c = 886.4(1) pm, Z = 4, dc = 2.92 Mg m-3, R = 0.052 for 755 reflections, and of SrBr2 · 1 H2O, orthorhombic, Pnma, a = 1146.4(1), b = 429,5(1), c = 922.9(1) pm, Z = 4, dc = 3.88 Mg m-3, R = 0.056 for 762 reflections have been determined from a Patterson synthesis and refined by Fourier and Least Squares methods. The structure consists of [SrX2 = H2O]n-layers normal to [100] and Sr—H2O—Sr—H2O-chains parallel [010]. The Sr—O distances are 265.1(3) pm, SrCl2 · 1 H2O, and 265.9(4) pm, SrBr2 · 1 H2O. The shortest Sr—Cl and Sr—Br distances (298.9(1) and 315.3(1) pm) are within the layers. The environment of oxygen and strontium is a distorted tricapped trigonal prism. The orientation of the water molecules has been determined from vibrational spectroscopic measurements. The hydrogen atoms H1 and H2 form bifurcated hydrogen bonds of different strength to neighbouring halide ions. The corresponding O···X distances are 331.9(4) and 320.2(4) pm, SrCl2 · 1 H2O, and 340.8(4) and 333.8(4) pm, SrBr2 · 1 H2O. The other O—X distances are between 310.3(5) and 323.7(5) pm, SrCl2 · 1 H2O, and 323.5(5) and 333.2(6) pm, SrBr2 · 1 H2O.
    Notes: Die Strukturen des SrCl2 · 1 H2O, orthorhombisch, Pnma, a = 1088,1(1), b = 416,2(1), c = 886,4(1) pm, Z = 4, drö = 2,92 Mg m-3, R = 0,052 für 755 Reflexe und des SrBr2 · 1 H2O, orthorhombisch, Pnma, a = 1146,4(1), b = 429,5(1), c = 922,9(1) pm, Z = 4, drö = 3,88 Mg m-3, R = 0,056 für 762 Reflexe wurden nach der Schweratommethode bestimmt und mit Fourier- und Least-squares-Verfahren verfeinert. Die Struktur besteht aus [SrX2 · H2O]n-Schichten senkrecht [100] mit Sr—H2O—Sr—H2O-Zick-Zack-Ketten parallel [010]. Die Sr—O-Abstände betragen 265,1(3) pm beim SrCl2 · 1 H2O und 265,9(4) pm beim SrBr2 · 1 H2O. Die kürzesten Sr—Cl- und Sr—Br-Abstände (298,9(1) bzw. 315,3(1) pm) liegen innerhalb der Schichten. Die Umgebung des Sauerstoffs und des Strontiums ist verzerrt tricapped-trigonal-prismatisch. Die Orientierung der Kristallwassermoleküle konnte mit Hilfe schwingungsspektroskopischer Messungen bestimmt werden. Die Wasserstoffatome H1 und H2 bilden verzweigte, unterschiedlich starke Wasserstoffbrücken zu benachbarten Halogenidionen aus. Die entsprechenden O···X-Abstände sind 331,9(4) und 320,2(4) pm beim SrCl2 · 1 H2O bzw. 340,8(4) und 333,8(4) pm beim SrBr2 · 1 H2O. Die übrigen O—X-Abstände liegen zwischen 310,3(5) und 323,7(5) pm beim SrCl2 · 1 H2O bzw. 323,5(5) und 333,2(6) pm beim SrBr2 · 1H2O.
