Abstract

New triangular cluster (Ph4P)2[Mo3S7(TBC)3] (2) (TBC—tetrabromocatecholate) was synthesized by the straightforward reaction of ( n Bu4N)2[Mo3S7Br6] (1) with tetrabromocatechol in the presence of Et3N, followed by the addition of Ph4PBr. Interaction of 2 with PPh3 leads to the conversion of the bridging disulphide ligands to the bridging sulphides, and (Ph4P)2[Mo3S4(TBC)3(thf)2]·0.5Et2O (3·0.5Et2O) was crystallized out of a THF/Et2O mixture. The main structural feature of 3 is unsymmetrical environment of the Mo3 core derived from the coordination of only two THF molecules per three metals.
