15)]2 was found to crystalline monoclinically, space group C2/c, with a = 31.687(3)Å, b = 12.216(2)Å, c = 22.414(2)Å, β = 135.006(7)° at 173 K and Z = 8. In soldi state, the asymmetric unit contains two molecules which are bonded via one intermolecular hyrogen bond. Twosuch dimer interact by two additional hydrogen bonds, giving a tetramer. In contrast to former results found with Cp2Ti(CH3)2, there
[(μ-OH)Rh(COD-,15)] 2被单晶结晶,空间群C2 / c,a = 31.687(3)Å,b = 12.216(2)Å,c = 22.414(2) Å,在173 K时β= 135.006(7)°,Z =8。在soldi状态下,不对称单元包含两个通过一个分子间氢键键合的分子。两个这样的二聚体通过另外两个氢键相互作用,得到四聚体。与以前的Cp 2 Ti(CH 3)2结果相反,[(μ-OH)Rh(COD-1,5)] 2与Cp 2 ★ Ti(CH 3)2之间没有反应。。羟基铑配合物与Cp 2 Ti [P(CH 3)3 ] 2反应,形成配合物配体分布,反应并形成CpRH(COD-1,5)和CpRh [P(CH 3)3 ]。2。
