Reaction of VCL3, MnCl2 and CrCl3+Zn with [Fe2S2(CO)6]2−, from reduction of [Fe2S2(CO)6] by LiEt3BH, resulting in pentanuclear mixed metal clusters [VFe4S4(CO)12] (1), [Et4N]2[MnFe4S4(CO)12] (2) and [Et4N]2[CrFe4S4(CO)12] (3), respectively. Complexes 1, 2 and 3 have been characterized by elemental analysis, spectroscopy and the crystal structures of 1 and 2 have been determined by X-ray crystallography. The structures of 1 and 2 contain a penta-nuclear M–Fe–S core, [Fe2S2MS2Fe2]z− (M=V, z
