Abstract

The title complex, (C24H20P)(2)[WZnS4(S-6)]center dot C3H6O or (Ph4P)(2)-[WS2(mu-S)(2){Zn(S-6)}] center dot Me2CO, was unexpectedly obtained on attempted recrystallization of a mixed tungten-zinc complex of a tris(pyrazolato) borate ligand. The two metal centres of the anion have distorted tetrahedral coordination and the two tetrahedra share one S center dot center dot center dot S edge; tungsten is additionally coordinated by two terminal sulfide ligands and zinc by a chelating S-6(2-) ligand, which has one central S-S bond significantly longer than the other four, a pattern found to be consistent for this ligand. This is the first reported example of a tetrahedral zinc centre bridging an edge of a single tetrathiotungstate( VI) or tetrathiomolybdate(VI) anion, although there are many previous examples with other metals.
