Nickel(II) Phosphane- and N-heterocyclic Carbene Complexes with Tridentate, Dianionic [S,N,O]2 - Ligands: Nickel(II) Phosphane- and N-heterocyclic Carbene Complexes with Tridentate, Dianionic [S,N,O]2 - Ligands

摘要
Square-planar dinuclear nickel(II) complexes containing [S,N,O](2-) ligands formed by condensation of acetyl acetone or benzoyl acetone with cysteamine were prepared. These dimeric nickel(II) compounds undergo bridge-cleavage reactions with the cage phosphine PTA (PTA = 1,3,5-triaza-7-phosphaadamantane) or in situ generated N-heterocyclic carbenes. The resulting diamagnetic, square planar Ni-II complexes were characterized by spectroscopic methods and X-ray diffraction.
