The reactions of the zerovalent carbonyl complexes, M(CO)6, M(CO)5(Rpy), M(CO)4(Rpy)2 (M = Mo, W, R = 2-Me, H) with a series of potentially mono- or bi-dentate uninegative (S,X)-donor ligands (S,X = xanthates, dithiocarbamates, pyridine-2-thiol, P,P-diphenyl-N-phenylphosphinothioformomido, P,P-diphenylphosphinedithioformamide) have given two types of anionic complexes: [M(S,X)(CO)5]− and [M(S,X)(CO)4]−
零价羰基配合物M(CO)6,M(CO)5(Rpy),M(CO)4(Rpy)2(M = Mo,W,R = 2-Me,H)与一系列化合物的反应潜在地单-或二齿uninegative(S,X)端供体配位体(S,X =黄原酸酯,二硫代氨基甲酸酯,吡啶-2-硫醇,P,P二苯基ñ -phenylphosphinothioformomido,P,P -diphenylphosphinedithioformamide)给两种类型的阴离子配合物:[M(S,X)(CO)5 ] -和[M(S,X)(CO)4 ] -(M = Mo 0,W 0)。这些分别含有(S,X)-配体作为单齿或双齿基团的阴离子被分离为其四苯基phosph盐或三乙基铵盐。描述了其中一些物种与烯丙基溴和HgX 2的反应。确定了[PPh 4 ] [W(S 2 COEt)(CO)5 ]的晶体结构。该晶体是单斜晶系,空间群P 2 1 / Ñ与一个14
