摘要
A new asymmetric phenol-based "end-off" dinucleating ligand HL was prepared using a modified methodology through a four-step synthesis. The ligand comprises two different coordination moieties, namely, a rigid 1,4-dimethyl-1,4,7-triazacyclononane unit and a more flexible N-(2-pyridyl)methyl-N-2-(2-pyridylethyl)amine unit. Its dinuclear Ni(II) complex containing two phosphate esters in a mu-I center dot(2) binding mode was synthesized and characterized by X-ray crystallography, in which each nickel atom is six-coordinate and adopts a slightly distorted octahedral coordination geometry.
