Abstract A mixture of three isomeric clusters of composition Mo3WS4(Et2PS2)6 (3) is obtained by reacting equimolar quantities of Mo3S4(Et2PS2)4, W(CO)3(CH3CN)3 and [Et2P(S)]2S2 in toluene'. Some NMR-spectroscopic data and the magnetic properties of these isomers are reported. Isomer 3a consists of a distorted cubane Mo3WS4, each metal of which is coordinated by six S atoms: three of them belonging to the cubane, one to a bridging and two to a chelating ligand Et2PS2-. The crystal structure of isomer 3b is reported. In 3b only three of the metals in the core are coordinated in this manner while the fourth is surrounded by three S of the cubane and three S of bridging ligands. 3b crystallizes in the orthorhombic space group Pbca, Z = 8. lattice parameters a = 2184,4(8), b = 2264,4(9). c = 2388.2(8) pm. The crystal structure was refined to R = 0.05 using 5398 observed reflections. By HPLC 3b can be separated into two isomers. 3b1 and 3b2, both differing in the type of metal.
