Cr(S2CNEt2)3. Tungsten hexacarbonyl, under the same conditions, gives rise to WSe2(S2CNEt2)3·0.5H2O (1) and [W(S2CNEt2)4]2W6O19 (2). The structures of 1 and 2 were established by X-ray structural analysis. The tungsten in complex 1 has a distorted dodecahedron coordination. The structure of 2 is ionic, and contains the well known W6O192− anion and the W(S2CNEt2)4+ cation containing dodecahedral tungsten.
摘要
六羰基铬在Me3NO·2H2O存在下与(Et2
NCS2)2Y(YSe,Te)反应形成Cr(S2CNEt2)3。在相同条件下,
六羰基钨会生成WSe2(S2CNEt2)3·0.5H2O(1)和[W(S2CNEt2)4] 2W6O19(2)。通过X射线结构分析确定1和2的结构。配合物1中的
钨具有十二面体的扭曲配位。2的结构为离子型,并且包含众所周知的W6O192-阴离子和包含十二面体
钨的W(S2CNEt2)4+阳离子。
