摘要

The asymmetrical tridentate Schiff base (H₂L = (E)-N′-(2-hydroxybenzylidene)-4-hydroxybenzohydrazide) has been designed and synthesized. The four transition metal complexes with this ligand [Cu(HL)(NO₃)](H₂O) (1), [Zn₂(HL) ₂(bipy)(H₂O)₂](NO₃)₂ (2), [Cu(HL)(H₂O)]₂(NO₃)₂ (3) and [Cu(HL)(Me₂NCO)]₂ (4) have been studied. The unsaturated coordination site of metal ion in complexes 1 and 2 is occupied by secondary ligand of nitrate and 4,4′-bipyridine. The crystal structure of complex 1 exhibits supramolecular framework with homochirality. Complexes 3 and 4 are dinuclear complexes bridged by the phenol oxygen atoms and the fifth coordination is occupied by H₂O molecular and DMF anion respectively. Hydrogen bonding and π-π stacking exist in all four complexes to construct supramolecular architecture.
