Abstract

The reaction of [Et4N]2[Fe3(mgr 3-Q)(CO)9] (Q=Se ([Et4N]2[1b]), Te ([Et4N]2[1c])) with [Cp*M(CH3CN)3][CF3SO3]2 (M=Rh, Ir) leads to the addition of a Cp*M2+ unit to a Fe2Q face of the initial cluster. In this way four new heteronuclear clusters [MFe3(mgr 4-Q)(CO)9Cp*] (M=Rh (2b, c); M=Ir (3b, c)) were obtained possessing a butterfly-shaped cluster core bridged by a mgr 4-Q unit. Furthermore, ...
