[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.
