Synthesis and characterization of (PPr3i)2(CO)HRu(µ-H)- (µ-OMe)Ir(cod): an unusual example of a heterometallic complex containing a mixed hydrido–alkoxide bridge

Abstract

The complex (PPr₃ⁱ)₂(CO)HRu(µ-H)(µ-OMe)Ir(cod) (cod=cycloocta-1,5-diene) was obtained by treatment of RuH₂(CO)(PHPh₂)(PPr₃ⁱ)₂ with [Ir(µ-OMe)(cod)]₂. The structure of this heterodinuclear compound has been determined by X-ray diffraction analysis. The molecule is dinuclear and consists of a distorted square-planar coordination around iridium and a distorted octahedral coordination around ruthenium connected through a mixed hydrido–methoxy bridge. The Ru–Ir separation is 2.8635(5) Å.
