A reactive and versatile trirhenium carbonyl cluster obtained by oxidation of [re3 (μ-H)4 (CO)10]−. Synthesis, x-ray characterization and reactivity of re3 (μ-H)3 (CO)10(NCMe)2
Oxidation of [Re3(μ-H)4(CO)10]− with CF3SO3H in acetonitrile gives the new complex Re3(μ-H)3(CO)10(NCMe)2. This contains a triangle of metal atoms with the edges bridged by the hydrides (mean ReRe 3.266 Å). The acetonitrile ligands, bound to two metals in a trans-diaxial manner, are easily replaced, giving a variety of derivatives.
CF 3 SO 3 H在乙腈中氧化[Re 3(μ-H)4(CO)10 ] -,得到新的络合物Re 3(μ-H)3(CO)10(NCMe)2。它包含一个金属原子的三角形,其边缘由氢化物桥接(平均ReRe3.266Å)。以跨双轴方式与两种金属键合的乙腈配体很容易被取代,得到各种衍生物。
