Über die Darstellung S, S-verbrückter Zweikern-Molybdän(V)-Komplexe. Kristall- und Molekularstruktur von [Mo2S4(Et2dtc)2]MoO42- wird von Diäthyldithiocarbaminat in wäßriger Lösung reduziert. Die zentrale Einheit MoO2S22+ des gebildeten [Mo2VO2S2(Et2dtc)2] weist eine große Bildungstendenz auf. [Mo2VS4(Et2dtc)2] läßt sich aus [Mo2V(S2)6]2- erhalten (Röntgenstrukturkturdaten vgl. Abstract).
Notes:
MoO42- is reduced by diethyldithiocarbamate (Et2dtc-) on prolonged digestion in aqueous medium whereby the complex [Mo2VO2S2(Et2dtc)2] is formed. The central moiety Mo2O2S22+ has a high formation tendency. When [Mo2V(S2)6]2- is refluxed with Et2dtc- in ethanol, [Mo2VS4- (Et2dtc)2] is formed, the X-ray crystal structure of which has been determined (space group P212121, a = 10.550(2) Å, b = 13.820(5) Å, c = 14.723(12) Å, dc = 1.90 g · cm3-, Z = 4). The Mo—Mo distance of the diamagnetic compound is 2.817(2) Å and the average Mo=St distance 2.099(4) Å.
