Reactions of phthalonitrile and terephthalonitrile with Ni(cod)(bpy) in a THF solution at room temperature lead to oxidative addition of the C-CN bond to give square-planar Ni(CN)(o-C₆H₄CN)(bpy) (3) and Ni(CN)(p-C₆H₄CN)(bpy) (4) respectively. Data from elemental analysis, as well as their IR and NMR spectra, agree with the structures. Crystal structures of the complexes 3 and 4 have been determined by X-ray crystallography.
