Transitional Metal Complexes with 1,2,4-Triazole Ligand: Syntheses and Crystal Structures

摘要

Four novel transitional metal complexes with 3-(4-pyridly)-4-phenyl-5-sulfhydryl-1,2,4-triazole(HL1)and 3-(3-pyridly)-4-phenyl-5-sulfhydryl-1,2,4-triazole(HL2)were synthesized and characterized by elemental analysis,IR and X-ray diffraction.Complexes 1,3 and 4 have two-dimensional(2-D)neutral rhombohedral grid with a(4,4)topology.In 1,3 and 4,all the metal ions are six-coordinated to four nitrogen atoms of four distinct ligands and two O atoms from water molecules.Complex 2 has tetranuclear Cu4Cl4units which are interconnected by four desulfurization ligands(L1-S)via Cu–N bonds to form a 2-D layer with(4,4)topology.
