摘要：

The reactions of [M( CC6H2Me3-2,4,6)X(CO)(2)(L)(2)] (M = MO W; X = Cl, Br; L = pyridine, 3,5-dimethylpyrazole) with Na[H2B(mt)(2)] (mt = methimazolyl) are metal dependent, providing either the alkylidyne complex [MO( CC6H2Me3-2,4, 6)(CO)(2){kappa(3)-H,S,S'-H2B(mt)(2)}] or the bis(chelate) complex [W(CO){kappa(2)-S,S'-H2B(mt)(2)}{kappa(2)-H,S,S'-H2B(mt)(2)}], the latter featuring both bi and tridentate coordination modes for the H2B(mt)(2) ligand.
