Copper(Ⅱ) complexes Cu(C6H6N2)2(ClO4)2 (1) and Cu2(OAc)4(C5H5ClN2)2 (2) with amino pyridine derivatives ligands have been synthesized and characterized by elemental analysis and IR spectrum. Their crystal structures are determined by X ray diffraction method. Compound 1, C12H16Cl2CuN4O8, Mr=478.73, triclinic, space
