α-Diimine nickel complexes of ethylene and related alkenes

A series of nickel mono(alkene) complexes, [LNi(alkene)], which consist of nickel(0) and neutral alpha-diimine ligand L (L = [(2,6-iPr(2)C(6)H(3)) NC(Me)](2)), have been synthesized. The bonding and structures of the complexes were studied by X-ray diffraction, spectroscopic methods, and DFT computations.
