The role of the second coordination sphere of [Ni(PCy2NBz2)2](BF4)2 in reversible carbon monoxide binding
This paper reports our investigations on the reactivity of a series of [Ni(diphosphine)2]2+ derivatives, including [Ni(PCy2NBz2)2](BF4)2, 1, with an atmosphere of carbon monoxide at room temperature. Complex 1 showed a unique ability to form a CO adduct under these conditions, and further characterization of this product has been carried out. A systematic study of the factors that favor formation of the CO adduct suggest that two bases in the second coordination sphere interact with the coordinated CO ligand to provide a stabilizing influence, and the generality of such an effect in this system is discussed. The effect of carbon monoxide on the catalytic activity of 1 for hydrogen oxidation has also been studied. D. L.
