Cleavage of phenolato-bridged nickel(II) centers in square planar coordination geometry by addition of trimethylphosphine affords mononuclear methylnickel complexes of coordination number five. The trimethylphosphine-supported trigonal bipyramidal methyl nickel(II) complex has a hard/soft chelating ligand with a phenolato oxygen atom and a π-coordinated olefin functional group. The chemical reactivity of complexes with these novel hard/soft chelating ligands remains to be clarified. ER -
