Hydrothermal synthesis, crystal structures and properties of zinc(2) Di-Nuclear complex and copper(1) coordination polymer based on building block 2-Phenyl-4,6-Di(pyridin-2-yl)pyrimidine

Abstract

A tetradentate ligand of 2-phenyl-4,6-di(pyridin-2-yl)pyrimidine (L) has been synthesized and its complexes with ZnI2 and CuI have been obtained by hydrothermal method. single crystal X-ray diffraction analysis indicates that ligand L coordinates with Zn(2) ions to form a simple four-coordinate di-nuclear complex, while the complexation of L with Cu(1) constructs a one-dimensional chain polymer. The existence of I-ion hampers the L to assemble grid-type complexes with Zn(2) and Cu(1). Fluorescence spectra show that the L emits blue fluorescence while its Cu(1) polymer decrease the fluorescence intensity and Zn(2) complex quenches the fluorescence.
