Two polynuclear transition metal complexes with a monodentate heterocycle and tridentate Schiff base ligands have been synthesized and characterized by elemental analysis,IR,UV and X-Ray diffraction.One is nickel(Ⅱ) complex [Ni(L1)(Mf)] (1) with 5-chlorosalicylaldehyde 4-nitrobenzoylhydrazone (H2L1) and morpholine (Mf),the other is copper(Ⅱ) complex [Cu2(L2)2(Py)2] (2) with 5-chlorosalicylaldehyde salicyloylhydrazone (H2L2) and pyridine (Py).In compound 1,the Ni (Ⅱ) ion is coordinated by three donors (phenolate-O,imine-N and deprotonated amide-O atoms) from the ligand L12- and the N atom of the neutral morpholine,forming a squareplanar N2O2 coordination geometry.In the crystal,every two molecules related by centrosymmetric operation in compound 1 are connected through intermolecular hydrogen bonds,forming one-dimensional chain.There are two crystallographically binuclear copper(Ⅱ) units in complex 2.The two metal centres are bridged by the phenolate O atoms of the neighboring ligand,forming two Cu2O2 quadrangle.Each Cu(Ⅱ) ion has a square-pyramidal geometry.CCDC:846209,1; 846210,2.
