    Notes: AgClO4 reacts with bidentate ligands 2-(methylthio)pyridine (SMepy) or complexes PPN[Au(Spy)2] [PPN = N(PPh3)2, HSpy = pyridine-2(1H)-thione) or PPN[Au(Sbz)2] (HSbz = benzoxazole-2(3H)-thione), themselves acting as ligands, to give dinuclear complexes [Ag2(μ-SMepy)2](ClO4)2 (1), [AgAu(μ-Spy)2] (2), or [AgAu(μ-Sbz)2] (3), respectively. By treating 1 with [AuCl(tht)] (tht = tetrahydrothiophene), [Au(SMepy)(tht)]ClO4 (4) is obtained which, in turn, reacts with SMepy to give [Au(SMepy)2]ClO4 (5). Similarly, [PdCl2(NCPh)2] reacts with SMepy in 1:1 molar ratio to give [Pd2Cl2(μ-Cl)2(SMepy)2] (6) which reacts with SMepy in 1:2 molar ratio to give [PdCl2(SMepy)2] (7). On the other hand, HSpy reacts with Ag2CO3 to give [Ag2(μ-Spy)2] (8), and (SMepyH)ClO4 reacts with [Au(acac)PPh3] (acacH = acetyl-acetone) to give [Au(SMepy)PPh3]ClO4 (9).

    Notes: 4-Butoxynitrobenzene reacts with [Hg(O2CCF3)2] and LiCl to give [Hg(R)Cl] [R = C6H3NO2-3, OnBu-6 (1)] which is symmetrized by Me4NCl to give [HgR2] (2), the crystal structure of which has been determined. The reaction of 2 with Me4N[AuCl4] affords Me4N[Au(R)Cl3] (3) by a facile transmetallation process. Complex 3 reacts with PPh3 (1:1) to give cis-[Au(R)(PPh3)Cl2] (4). The diaryl complex [-Ph-2)(R)Cl] (5) is obtained by reaction of 3 with [Hg-(C6H4N=NPh-2)2] through a second transmetallation reaction. Complex 5 and PPh3 (1:1) give [AuClPPh3] and the C-C coupling biphenyl RC6H4N=NPh-2 (6).

    Notes: The formylarylmercury(II) complex [Hg{C6H(CHO)-6-(OMe)3-2,3,4}2] reacts with 4-butylaniline (1:2) to give [Hg{C6H(CH=NC6H4C4H9-4′)-6-(OMe) 3-2,3,4}2] (1) by a condensation reaction. This complex reacts with Me4-N[AuCl4] (1:1) to give [Hg{C6H(CH=NC6H4C4H9-4′)-6-(OMe) 3-2,3,4}Cl] (2) and the monoarylgold(III) compound cis-C6H4-nBu-4′)-6-(OMe)3-2,3,4}Cl2] (3). This complex reacts with PPh3 (1:1) to give the adduct cis-[Au{C6H(CH=NC6H4-n, Bu-4′)-6-(OMe)3-2,3,4}Cl2(PPh3)] (4) and with AgClO4 (1:1) in acetone to give the ketonyl complex cis-[C6H4-nBu-4′)-6- (OMe)3-2,3,4}-{CH2C(O)Me}Cl] (5). cis-Me4N[Au(C6H4NO2-2)2Cl 2] react with [Hg{C6H3(N=NC6H4OMe-4′)-2-(OMe)-5}Cl] and Me4NCl (1:1:1) to give cis-[C6H4OMe-4′)-2- (OMe)-5}(C6H4NO2-2)2] (6): Similarly, cis-Me4N-[Au(C6H4CF3-2)2 Cl2] (7), obtained by treating [Hg(C6H4CF3-2)2] with Me4N[AuCl4] and Me4NCl (1:1:1), reacts with [Hg(C6H4CH2NMe2-2)Cl] and Me4NCl (1:1:1) to give the triarylgold(III) complex cis-[Me2-2)(C6H4CF3-2)2] (8). This complex can also be obtained by treating cis-[Me2-2)Cl2] with [Hg(C6H4CF3-2)2] and Me4NCl (1:1:1). The crystal structure of 3 reveals the presence of two independent molecules, in one of which the butylphenyl group is disordered. The geometry at the gold atom is square planar; distortions may be attributed to the narrow bite angle and steric repulsion between a chloride ligand and the ortho-methoxy group. The greater trans influence of the aryl ligand causes a great difference in Au-Cl bond lengths.

    Structural Characterization and Magnetic Behaviour of the Ferro-Antiferromagnetic Alternating Manganese-Azido Chain [Mn(3-Et,4-Mepy)2(μ-N3)2]n (3-Et,4-Mepy = 3-Ethyl-4-methylpyridine) (1999)

    Notes: The ligands 3-ethyl-4-methylpyridine (3-Et,4-Mepy) and azide coordinate to MnII forming an alternating chain with the formula [Mn(3-Et,4-Mepy)2(μ-N3)2]n. This compound crystallizes in the space group P-1. The compound consists of chains of octahedrally coordinated manganese atoms alternately bridged by double end-to-end (μ1,3) and double end-on (μ1,1) azido bridges, which results in a structurally and magnetically alternating chain. The 3-ethyl-4-methylpyridine ligands are arranged trans, completing the six-fold coordination spheres of the manganese atoms. The Mn-Mn distances are distinctly different: Mn(1)-Mn(1A) = 5.149(3) Å (double end-to-end azido bridge) and Mn(1)-Mn(1B) = 3.402(2) Å (double end-on azido bridge). The magnetic properties of the compound, as studied in the temperature range 300-4 K, show bulk antiferromagnetic interaction. Fitting of the magnetic data by using an equation for alternating ferro-antiferromagnetic S = 5/2 1-D systems gives the parameters JAF = -13.7(1) cm-1, JF = 2.4(1) cm-1, g = 2.036(2).

    Description / Table of Contents: Reaction of Molybdenum Pentachloride with (SCN)2, (SeCN)2, and ICNBy reaction of MoCl5 with (SCN)2, (SeCN)2, and ICN in CCl4 or H2CCl2 the compounds MoCl5(NCS)2, MoCl5(NCSe)2, and MoCl5NCI were obtained. They are very sensitive towards hydrolysis and decompose on heating. The compounds are characterized by their vibrational and EPR spectra which indicate that the pseudohalogen is bonded via a nitrogen atom.
    Notes: Durch Reaktion von MoCl5 mit (SCN)2, (SeCN)2 bzw. ICN in CCl4 oder H2CCl2 wurden die Verbindungen MoCl5(NCS)2, MoCl5(NCSe)2 und MoCl5NCI erhalten. Sie sind sehr hydrolyseempfindlich und zersetzen sich beim Erhitzen. Die Verbindungen wurden durch ihre IR-und ESR-Spektren charakterisiert. Danach ist das Pseudohalogen über ein N-Atom an das Molybdän-koordiniert.

    Description / Table of Contents: Die Reaktion des SnCl2 mit Br2 und I2 in schwachen Donor-LösungsmittelnEs wurden die Verbindungen SnCl2Br2(MeCN)2, “Sn3Cl8Br4(THF)6” und “Sn3Cl10Br2(OEt)6” durch Reaktion zwischen SnCl2 und Br2 in Acetonitril (MeCN), Tetrahydrofuran (THF) und Diethylether (OEt2) gewonnen. Die zwei letzten Verbindungen sind feste Lösungen von SnCl4L2 und SnCl2Br2L2 (L = THF, OEt2) jeweils im Verhältnis 1:2 und 2:1. Die Verbindungen wurden mit Hilfe von IR-, Raman- und Mößbauer-Spektroskopie charakterisiert. Es wurde C1-Symmetrie für SnCl2Br2(MeCN)2 und C2v mit den Liganden in trans-Position für SnCl2Br2L2 (L = THF, OEt2) gefunden. Das bisher nicht bekannte Mößbauer-Spektrum des SnBr4(THF)2 wurde gemessen und ebenfalls die Reaktion zwischen SnCl2 und I2 in denselben Lösungsmitteln studiert. Die Bildung des SnCl4L2 (L = MeCN, THF, OEt2) SnI4 und einer kleinen Menge des SnI3Cl wurde beobachtet und Raman-spektroskopisch identifiziert.
    Notes: The compounds SnCl2Br2(MeCN)2, “Sn3Cl8Br4(THF)6”, and “Sn3Cl10Br2(OEt2)6” were obtained by reaction between SnCl2 and Br2 in acetonitrile (MeCN), tetrahydrofuran (THF) and diethyl ether (OEt2). The two last are solid solutions of SnCl4L2 and SnCl2Br2L2 (L = THF, OEt2) in the proportions 1:2 and 2:1, respectively. The compounds are characterized by IR, Raman, and Mössbauer spectroscopy, a C1 symmetry being found for SnCl2Br2 (MeCN)2 together with a C2v symmetry, with the ligands in trans positions, for SnCl2Br2L2 (L = THF, OEt2). The Mössbauer spectrum of SnBr4(THF)2 was also obtained, which has not previously been reported. The reaction between SnCl2 and I2 has also been studied in the same solvents, and the formation of SnCl4L2 (L = MeCN, THF, OEt2), SnI4, and a small amount of SnI3Cl was observed, which have been identified by Raman spectroscopy.
