A dinuclear Mo2H8 complex supported by bulky C5H2tBu3 ligands

Abstract

Hydride-bridged transition metal complexes have been found to serve as suitable precursors for the activation of small molecules without the use of reducing agents. In this study, we synthesized a dinuclear Mo₂H₈ complex supported by bulky C₅H₂^tBu₃ (Cp^‡) ligands, Cp^‡₂Mo₂H₈ (1), from the reaction of Cp^‡MoCl₄ with KC₈ under H₂. The hydrides of complex 1 can be replaced with benzene at 60 °C to afford a μ-benzene complex Cp^‡₂Mo₂H₂(μ-C₆H₆) (2).
