title: Nickel(II) complexes of the new pincer-type unsymmetrical ligands PIMCOP, PIMIOCOP, and NHCCOP: versatile binding motifs.
abstract: Chelation/nickellation of an unsymmetrical meta-phenylene-based ligand featuring phosphinite and imidazolophosphine functionalities gives the corresponding pincer complex. N-Methylation of the latter generates a new complex featuring the ternary moiety NHC→Ph(2)P(+)→Ni, which can be converted subsequently into the binary moiety NHC→Ni by extrusion of Ph(2)P(+), thus allowing a sequential synthesis of pincer complexes displaying varying degrees of dipolar character.
