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 group , a=0.7641(1)nm, b=0.7987(1)nm, c=0.7990(1)nm, α =106.78(1)° ,β =95.71(1)° , γ =108.85(1)° , V=0.4317(1)nm3, Z=1, Dc=1.841g· cm- 3, μ =1.627mm- 1, F(000) =243,R1=0.0264, ω R2=0.0641 (I >2σ (I)). In 1, the center metal ion Cu? possesses distorted octahedral geometry. Compound 2, C18H22C12Cu2N4O8, Mr=620.38,monoclinic, space group C2/c, a=1.9888(3), b=0.9158(1), c=1.4241(2)nm, β =115.89(1)° , V=2.3336(5)nm3, Z=4, Dc=1.766mg· cm- 3, μ =2.104mm- 1, F(000)=1256, R1=0.0263, wR2=0.0676 (I >2σ (I)). Compound 2 is dinuclear structure, in which each Cu? adopts five coordinated distorted square pyramid geometry. CCDC: 193109; 193110.
