摘 要: | Copper(Ⅱ) complexes Cu(C6H6N2)2(ClO4)2 (1) and Cu2(OAc)4(C5H5ClN2)2 (2) with amino-pyridine deriva-tives ligands have been synthesized and characterized by elemental analysis and IR spectrum. Their crystal struc-tures are determined by X-ray diffraction method. Compound 1, C12H16C12CuN4O8, 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, ωR2=0.0641 (I>2σ(I)). In 1, the center metal ion Cu(Ⅱ) 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(Ⅱ) adopts five-coordinated distorted square pyramid geometry. CCDC: 193109; 193110.
