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)2κ3-H,S,S′-H2B(mt)2}] or the bis(chelate) complex [W(CO)κ2-S,S′-H2B(mt)2}κ3-H,S,S′-H2B(mt)2}], the latter featuring both bi and tridentate coordination modes for the H2B(mt)2ligand.
摘要[M(CC6H2Me3-2,4,6)X(CO)2(L)2](M = Mo,W; X = Cl,Br; L =吡啶,3,5-二甲基吡唑)与Na的反应[H2B(mt)2](mt =甲him唑)是金属依赖性的,提供亚烷基配合物[Mo(CC6H2Me3-2,4,6)(CO)2 κ3-H,S,S'-H2B(mt) 2}]或双(螯合物)复合物[W(CO)κ2-S,S'-H2B(mt)2} κ3-H,S,S'-H2B(mt)2}],后者具有H2B(mt)2配体的双齿和三齿配位模式。
