Reaction of Mn2(CO)10 with R2P(S)P(S)R2 (R=Me, Et, Prn, Bun) in toluene at 120 °C yields binuclear [Mn2(CO)8(μ-PR2)2] and trinuclear [Mn(CO)3(μ-SPR2)]3 complexes. Both result from phosphorus–phosphorus bond scission, while in the former sulfur abstraction has also occurred. An X-ray diffraction study of [Mn2(CO)8(μ-PBun2)2] confirms that the manganese adopts a distorted octahedral geometry with local
Mn 2(CO)10与R 2 P(S)P(S)R 2(R = Me,Et,Pr n,Bu n)在甲苯中于120°C反应生成双核[Mn 2(CO)8( μ-PR 2)2 ]和三核[锰(CO)3(μ-SPR 2)] 3个络合物。两者都是由磷-磷键断裂引起的,而在前者中也发生了硫的抽象。[Mn的X射线衍射研究2(CO)8(μ-PBU Ñ 2)2]证实了锰采用具有局部C 2 v对称性的扭曲的八面体几何形状。
