SYNTHESIS AND CRYSTAL STRUCTURE OF COPPER(Ⅱ) COMPLEX BY OXIDATIVE ADDITION OF DIBENZOYL PEROXIDE ON METALLIC COPPER

在咪唑存在下利用铜粉和过氧化苯甲酰的氧化加成反应合成了铜(Ⅱ)配合物:[Cu(C_3H_4N_2)_2(_C6H_5COO)_2](C_3H4_N_2为咪唑).配合物晶体属于单斜晶系,空间群为P_2(1)/n,Mr=441.74,a=8.6799(4),b=9.540(6),C=12.399(5)A,α=v=90°,β=100.8°,V=1010.9A^3,Z=4,μ=21.4cm^(1-), D_c=1,654g·cm^(-3),R=0.033、Rw=0.042。通过红外光谱,电导,热分析及X-射线粉末衍射等方法,对配合物进行了表征。

Dibenzoyl peroxide undergoes oxidative addition on metallic copper with imidazole (C_3H_4N_2) in a mixed solvent (ethanol, methanol and tetrahydrofuran) and affords the copper complex Cu (C_3H_4N_2)_2(C_6H_5COO)_2. Crystals are monoclinic, Mr = 441.74, C_(20)H_(18)N_4O_4Cu, space group P2(l)/n, with cell parameters, a=8.699(4), b=9.540(6), c=12.399(5)A, α=γ=90°,β=100.8°, V=1010,9A^3 Dc=1.654g·cm^(-3),μ=21.4cm^(-1), Z=4.Characterization of the complex are studied by conductivity, TG spectra, IR spectra and X-ray powder diffraction.
