Abstract

[MoH(CO)₃(Cp)] reacts with [Zr(NEt₂)₄] in a 2:1 ratio at room temperature to give [Zr{Mo(CO)₃(Cp)}₂(NEt₂)₂(NHEt₂)]₂ (I) in 69% yield. Product I was characterized spectroscopically and by an X-ray diffraction study (R = 5.9%). The molecule is dimeric in the solid state, held together by two [Mo(μ-CO)₂(CO)(Cp)] bridges. Each zirconium atom coordinates to three “isocarbonyl” oxygens two diethylamides, and a diethylamine. NMR spectra suggest that I dissociates into symmetric monomers in benzene solution. Lewis bases, such as ethers, cleave the Zr-O bonds to give [Mo(CO)₃(Cp)]^- anions. Different mole ratios of [MoH(CO)₃(Cp)] and [Zr(NEt₂)₄] yield other mixed-metal products.
