Аннотация

New triangular cluster (Ph₄P)₂[Mo₃S₇(TBC)₃] (2) (TBC—tetrabromocatecholate) was synthesized by the straightforward reaction of (ⁿBu₄N)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.
