dimolybdenum complexes with bridging thiolato groups, (η5-C5H5)(CO)Mo(μ-SR)3Mo(CO)3 (4; R=Me, Ph, Bn (benzyl), Tol), were formed from Mo(CO)3(NCMe)3 and [C5H4SR]−. The related complex (η5-C5H5)(CO)Mo(μ-SR)3Mo(CO)(SR)2 (5; R=Ph) was obtained when additional [C5H4SR]− was used in the reaction. The molecular structures of 4 (R=Bn) and 5 were determined by X-ray crystallography. A Mo2Co complex (6) was obtained
具有桥接thiolato基四dimolybdenum络合物,(η 5 -C 5 H ^ 5)(CO)的Mo(μ-SR)3的Mo(CO)3(4 ; R = Me中,pH值,BN(苄基),TOL),分别为由Mo(CO)3(NCMe)3和[C 5 H 4 SR] -形成。相关复合物(η 5 -C 5 H ^ 5)(CO)的Mo(μ-SR)3的Mo(CO)(SR)2(5 ; R = PH)时附加的[C得到5 ħ 4 SR] -是在反应中使用。的分子结构通过X射线晶体学测定4(R = Bn)和5。甲沫2 Co络合物(6)从获得的(η 5 -C 5 H ^ 4 -李+)(CO)3莫科(CO)4且Ph 2的PCl。由X射线衍射数据确定的结构揭示了一些不寻常的桥接排列。
