title: Synthesis, structure, and reactivity of a nickel dihydrogen complex.
abstract: Hydrogen activation by nickel: A tBuPCP pincer ligand facilitates formation of cationic Ni(II)  dihydrogen and terminal dinitrogen complexes. The compounds have been characterized by X-ray crystallography and NMR spectroscopy. Addition of base promotes heterolytic cleavage of H(2)  to form the corresponding neutral hydride complex.
