摘　　要：At room temperature,dibenzoyl peroxide undergoes oxidative addition on metallic Copper Powder and 2-aminopyridine in a solvent(acetone and tetrahydrofuran), which affords the product as a binuclear Cu(II)complex [Cu (C5 H5 COO)2(C5 H5 N2)]2. (C4 H5 O)2. The structure of the complex was characterized by elemental analyses. IR spectra, TG-DTA. The structure of the compound has been solved by direct method and Fourier synthesis, and refined by block-diagonal and full matrix least-squares method to a final R of 0.04329 for 3671 independent reflection of I>e(I). The crystals are triclinic, C46H45N4O10Cu2.Z=1, Mr=943.93, space group P-1, with cell parameters, a=10.806(1); b=11.169(3);c=11.729(2)A; α=71.99(2),β=89.38(1)°; γ=81.37(1); V=1330.1A3; Dc=1.172g.cm-3;μ=8.5cm-1. The copper(II) ion is coordinated by four bridging bidentate benzoate and two 2-aminopyridine to form dimeric molecules.At room temperature,dibenzoyl peroxide undergoes oxidative addition on metallic Copper Powder and 2-aminopyridine in a solvent(acetone and tetrahydrofuran), which affords the product as a binuclear Cu(II)complex [Cu (C5 H5 COO)2(C5 H5 N2)]2.
