Abstract

The sequential treatment ofNa[H₂B(mt)₂] (mt = methimazolyl) with [Mo(pip)₂(CO)₄] (pip = piperidine), [Mo(CO)₃(L)₃] (L = NCMe, L₃ = η⁶-C₇H₈) and [AuCl(PPh₃)] provides the diheterotrimetallie complex [Mo₂Au{μ-H ₂B(mt)₂}(CO)₇PPh₃)] in which each thione group of the H₂B(mt)₂ ligand bridges two molybdenum centers, one of which is also involved in a 3-center, 2-electron B-H-Mo interaction. This complex is also obtained directly from [Mo(CO) ₃(η⁶-c₇H₈)] and [Au(PPh ₃){H₂B(mt)₂}] while the triheterotrimetallic species [MoWAu{μ-H₂B(mt)₂}(CO)₇(PPh ₃)] results from Na[H₂B(mt)₂], [W(CO) ₃(NCMe)₃], [Mo(pip)₂(CO)₄], and [AuCl(PPh₃)].
