Abstract

[C5Cl4Br]Mn(CO)3 reacts with butyllithium and Mn(CO)5Br or Au(PPh3)Cl to give the bimetallic cyclopentadienyl-bridged complexes [C5Cl4Mn(CO)5]Mn(CO)3 (1) and [C5Cl4Au(PPh3)]Mn(CO)3 (2), respectively. The molecular structures of 1 and 2 show no or very weak interactions between the metal centers. 1 reacts with BuLi and Au(PPh3)Cl in a formal substitution reaction to give 2. PPh3 replaces one CO ligand in 1 to yield [C5Cl4[Mn(CO)4(PPh3)]]Mn(CO)3 (3).
