Abstract: | 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, [Mo2VS (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. |
