ZnH₂ as a Precursor to Catalytically Active Ru-ZnH Heterometallic Complexes.

ABSTRACT: Reaction of [Ru(IPr)₂(CO)H][BAr^F₄] (1; IPr = 1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidene; BAr^F₄ = B{3,5(CF₃)₂C₆H₃}₄) with an excess of ZnH₂ in THF gives the structurally characterized neutral Ru(ZnH) complex [Ru(IPr)₂(CO)(ZnH)H₃] (6) and Ru(ZnH)₂ salt [Ru(IPr)₂(CO)(ZnH)₂H₃][BAr^F₄] (5). Crystallographic and computational analyses show the presence of both bridging Ru-H-Zn hydrides and terminal Ru-hydrides in the two products. Calculations also identify a low-energy H/ZnH exchange pathway that rationalizes the experimentally observed (EXSY) fluxionality of the
