M(CO)3Cl(η5-C5H5) and M(CO)3(PPh3)2Cl2(M = Mo, W) react with SPPh2H and Et3N to give M(CO)2-(η5-C5H5)(η2-SPPh2) and M(CO)2(PPh3)(η2-SPPh2)2, respectively; an X-ray crystal structure determination of Mo(CO)2(PPh3)(SPPh2)2 reveals a 7-co-ordinate pseudopentagonal bipyramidal geometry for the molybdenum atom with an almost planar configuration for the sulphur and phosphorus atoms.
M(CO)3Cl(δ-5-
C5H5)和 M(CO)3(PPh3)2Cl2(M = Mo、W)与
SPPh2H 和 Et3N 反应,分别生成 M(CO)2-(δ-5- )(δ-2-
SPPh2)和 M(CO)2(PPh3)(δ-2-
SPPh2)2;通过测定 Mo(CO)2(PPh3)(
SPPh2)2 的 X 射线晶体结构,发现
