    Notes: Die Zylindermethode nach Gouy gestattet bei Verwendung einer registrierenden Magnetwaage die kontinuierliche Aufzeichnung der Gewichtsänderungen, die eine Probe im Magnetfeld in Abhängigkeit von ihrer Temperatur erfährt. Eine Einrichtung zur automatischen, linearen Aufheizung der Probe von - 180 bis + 180°C wird beschrieben. In dem genannten Bereich kann so der Temperaturverlauf der magnetischen Suszeptibilität lückenlos aus den Meßkurven ermittelt werden.

    Description / Table of Contents: Synthesis, IR Spectrum, and Crystal Structure of Sb12O18(OH)2Cl22 · 2CH2Cl2The title compound has been prepared by the reaction of Sb5O7Cl11 with dichloromethane at 20°C, forming colourless, moisture sensitive crystals. Sb12O18(OH)2Cl22 · 2CH2Cl2 crystallizes monoclinically in the space group P21/n with two formula units per unit cell. Structure solution with 2696 unique observed reflections, R = 0.042. Lattice dimensions at 19°C: a = 1350.2, b = 1466.7, c = 1392.9 pm, b̃ = 97.925°. The distorted octahedrally coordinated antimony atoms, bridged by oxygen atoms, exhibit a molecular array which may be seen as a fragment of the rutile type structure, isolated by terminal chloride ligands. The solvate molecule is associated by a hydrogen bridge OH···Cl.
    Notes: Die Titelverbindung entsteht in Form farbloser Kristalle bei der Reaktion von Sb5O7Cl11 mit Dichlormethan bei 20°C. Sb12O18(OH)2Cl22 · 2CH2Cl2 kristallisiert monoklin in der Raumgruppe P21/n mit zwei Formeleinheiten pro Elementarzelle. Strukturlösung mit 2696 unabhängigen beobachteten Reflexen, R = 0,042. Gitterkonstanten bei 19°C: a = 1350,2; b = 1466,7; c = 1392,9 pm, b̃ = 97,925°. Die verzerrt oktaedrisch koordinierten und über Sauerstoffatome verbrückten Antimonatome bilden ein molekulares Gerüst, das als ein durch terminale Chlorliganden isolierter Ausschnitt aus der Rutilstruktur angesehen werden kann. Das Solvatmolekül ist durch eine Wasserstoffbrücke OH…Cl assoziiert.

    Description / Table of Contents: The Crystal Structures of the Vanadium Weberites Na2MIIVIIIF7 (MII = Mn, Ni, Cu) and of NaVF4At single crystals of the vanadium(III) compounds NaVF4 (a = 790.1, b = 531.7, c = 754.0 pm, β = 101.7°; P21/c, Z = 4), Na2NiVF7 (a = 726.0, b = 1031.9, c = 744.6 pm; Imma, Z = 4) and Na2CuVF7 (a = 717.6, b = 1043.5, c = 754.6 pm; Pmnb, Z = 4) X-ray structure determinations were performed, at Na2MnVF7 (a = 746.7, c = 1821.6 pm; P3221, Z = 6) a new refinement. NaVF4 crystallizes in the layer structure type of NaNbO2F2. The fluorides Na2MIIVF7 represent new orthorhombic (MII = Ni; Cu) resp. trigonal (MII = Mn) weberites. The average distances within the [VF6] octahedra of the four compounds are in good agreement with each other and with data of related fluorides (V—F: 193.3 pm). The differences between mean bond lengths of terminal and bridging F ligands are 5% in NaVF4, but less than 1% in the weberites. Details and data for comparison are discussed.
    Notes: An Einkristallen der Vanadium(III)-Verbindungen NaVF4 (a = 790,1, b = 531,7, c = 754,0 pm, β = 101,7°; P21/c, Z = 4), Na2NiVF7 (a = 726,0, b = 1031,9, c = 744,6 pm; Imma, Z = 4) und Na2CuVF7 (a = 717,6, b = 1043,5, c = 754,6 pm; Pmnb, Z = 4) wurden Röntgenstrukturbestimmungen durchgeführt, an Na2MnVF7 (a = 746,7, c = 1821,6 pm; P3221, Z = 6) eine neue Verfeinerung. NaVF4 kristallisiert in der Schichtstruktur des NaNbO2F2-Typs. Die Fluoride Na2MIIVF7 sind neue orthorhombische (MII = Ni; Cu) bzw. trigonale (MII = Mn) Weberit-Vertreter. Die mittleren Abstände in den [VF6]-Oktaedern der vier Verbindungen stimmen gut miteinander und mit Daten in verwandten Fluoriden überein (V—F: 193,3 pm). Die Unterschiede zwischen den mittleren Abständen terminaler und verbrückender F-Liganden betragen in NaVF4 5%, in den Weberiten aber weniger als 1%. Einzelheiten und Vergleichsdaten werden diskutiert.

    Description / Table of Contents: Relations of Distances and Coordination in the Layer Structures of the Ternary Fluorides K2MF4 and K3M2F7 (MII = Mg, Mn, Co=Zn)Results of X-ray single crystal structure refinements of the compounds K2MF4 (M = Mg, Mn, Co, Ni) and K3M2F7 (M = Mn, Co, Ni), all crystallizing in the tetragonal space group I4/mmm of the K2NiF4 and Sr3Ti2O7 type, resp., are reported. The distances obtained are discussed, including data of the compounds with M = Cu, Zn. The influence of the KF9 coordination is made responsible for the fact, that the octahedral MF6 dimensions are much the same as in the corresponding perovskites KMF3. The shortest K—F distance of this KF9 group, occuring in both layer structure types, decreases against lattice widening from 263.4 pm (K2MgF4) to 258.0 pm (K2MnF4). The charge ratio calculated from the KF9 coordination for the unlike bonded anions leads to a better balanced charge distribution in the K2MF4 type, as is obtained by applying Pauling's rules.
    Notes: Ergebnisse röntgenographischer Einkristallstrukturverfeinerungen an den im K2NiF4- bzw. Sr3Ti2O7-Typ kristallisierenden Verbindungen K2MF4 (M = Mg, Mn, Co, Ni) und K3M2F7 (M = Mn, Co, Ni), die alle der tetragonalen Raumgruppe I4/mmm angehören, werden mitgeteilt. Die resultierenden Abstandsdaten werden unter Einbeziehung der Verbindungen mit M = Cu, Zn diskutiert. Die weitgehend den zugehörigen Perowskiten KMF3 entsprechenden Abstandsverhältnisse in den MF6-Oktaedern werden dem Einfluß der KF9-Koordination zugeschrieben, deren kürzester Abstand K—F in beiden Schichtstrukturtypen entgegen der Gitteraufweitung von 263,4 pm (K2MgF4) auf 258,0 pm (K2MnF4) abnimmt. Das aus der KF9-Koordination berechnete Ladungsverhältnis der ungleich gebundenen Anionen führt zu einer ausgeglicheneren Ladungsbilanz für den K2MF4-Typ, als die Anwendung der Paulingschen Regeln.

    Description / Table of Contents: X-Ray Studies on Titanium(III) Fluoro Compounds with Pyrochlore-related StructuresThe cubic compounds (a/pm) CsMIITiIIIF6, MII = Mg (1041.6), Ni (1043.9), Zn (1049.8), Co (1051.7), V (1052.6), Fe (1055.3), Mn (1064.9) and CsM0,5ITi1,5IIIF6, MI = K (1074.6), Rb (1080.6) were prepared. They crystallize in the modified pyrochlore structure of the RbNiCrF6 type, which is confirmed once more at single crystals of an oxide fluoride phase CsTi2X6 (X6 between O2F4 and O3F3): Space group Fd3m, a = 1028.8 pm, R = 2.6% (126 independent reflections). Further compounds CsM0,5ITi1,5IIIF6 according to their powder diagrams are orthorhombic (MI = NH4: a = 764.1, b = 767.5, c = 1087.5 pm) or monoclinic (Na: a = 737.0, b = 758.0, c = 1061.8 pm, β = 91.1°, Li: a = 1466, b = 1479, c = 1041 pm, β = 93.3°) with related, but not exactly know structures.

Sie kristallisieren in der modifizierten Pyrochlorstruktur des RbNiCrF6-Types, der an Einkristallen einer Oxidfluoridphase CsTi2X6 (X6 zwischen O2F4 und O3F3) erneut bestätigt wird: Raumgruppe Fd3m, a = 1028,8 pm, R = 2,6% (126 symmetrieunabhängige Reflexe). Weitere Verbindungen CsM0,5ITi1,5IIIF6 sind nach Pulveraufnahmen orthorhombisch (MI = NH4: a = 764,1, b = 767,5, c = 1087,5 pm) bzw. monoklin (Na: a = 737,0, b = 758,0, c = 1061,8 pm, β = 91,1°, Li: a = 1466, b = 1479, c = 1041 pm,β = 93,3°), mit verwandten, aber nicht genauer bekannten Strukturen.
