Abstract: [Cd2(HL)2(ox)]·1.5H2O was synthesized hydrothermally from Cd(NO3)2·4H2O, pyrazolyl derivative(H2L=2,6-di-(5-phenyl-1H-pyrazol-3-yl)pyridine) and oxalate(H2ox=oxalic acid). Structural analysis revealed that the complex crystallized in the triclinic system with P-1 space group. The Cd took a distorted octahedral geometry and was coordinated by two oxygen atoms from one ox ligand and four N atoms from two HL- ligands. Adjacent Cd atoms(Cd1/Cd2) were connected through bridging ox ligand and N atoms from HL- to generate two separate 1D chains structure. The complex was further characterized by elemental analysis, IR, UV-Vis spectroscopy and powder X-ray diffraction(PXRD). In addition, the complex displayed ideal thermal stability and photoluminescent properties, and exhibited some catalytic activity toward the oxidation of cyclohexane.

Key words: bisphenyl-pyrazolyl-pyridine-oxalate cadmium complex, crystal structure, fluorescence and catalytic property
