摘要：

From the reaction between Rh-2(O(2)CBu(t))(4) and [Bu(4)(n)N][O(2)CMe] in toluene crystals of [Bu(4)(n)N](2)[Rh-8(O(2)Bu(t))(16)(O(2)CMe)(2)(toluene)(2)] have been obtained and structurally characterized. The [Rh-8(O(2)Bu(t))(16)(O(2)CMe)(2)(toluene)(2)](2-) anion is informative as a model for the nature of the species present in solution, namely [Rh-2(O(2)CBu(t))(4)] dimers, small oligomers, [Rh-2(O(2)CBu(t))(4)(eta(1)-O(2)CMe](-) anions and terminal [Rh-2] centres weakly solvated by toluene. Also of note is the kinetic inertness of the Rh-2(4+) centre to carboxylate exchange at 22 degrees C, which is in marked contrast to related Mo-2(4+) centres.
