摘    要:At room temperature, dibenzoyl peroxide undergoes oxidative addition reaction with metallic copper powder and pyridine N-oxide (triphenylphosphine oxide or 2,9-dimethyl-4,7-diphenyl-1,10-phenanthrolin) which affords the last products as binuclear copper(II) complexes, Cu(C5H5NO)-(C6H5COO)2]2(1), Cu(OPPh3)(C6H5COO)2]2(2) and Cu(C6H5COO)(C26H2oN2)](3, C26H2oN2 is 2,9-dimethyl-4,7-diphenyl-1,10-phenanthrolin). The structure of the complexes were characterized by elemental analyses, IR spectra, TG-DTA and magnetic property. Crystals(1) are triclinic, space group P1,a=0.92617(36),b=1.06973(17), c=1.08813(29) nm, a=59.60(2)°, β=74.83(3)°,γ=72.80(2)°, V=0.880 nm3, Dc=1.520 g/cm3, Z=1, R=0.044, Rw=0.048, Mr=805.78, 3477 reflections with I > 3σ(I). Each copper(Ⅱ) ion is coordinated by two bridging bidentate benzoate ligands and one pyridine N-oxide or triphenylphosphine oxide to form dimeric binuclear molecules. The structure of the compound(1) shows a clear centre of symmetry.

Abstract:At room temperature, dibenzoyl peroxide undergoes oxidative addition reaction with metallic copper powder and pyridine N-oxide (triphenylphosphine oxide or 2,9-dimethyl-4,7-diphenyl-1, 10-phenanthrolin) which affords the last products as binuclear copper(II) complexes, Cu(C5H5NO)-(C6H5COO)2]2(1), Cu(OPPh3)(C6H5COO)2]2(2) and Cu(C6H5COO)(C26H20N2)](3, C26H20N2 is 2,9-dimethyl-4,7-diphenyl-l,l~phenanthrolin). The structure of the Complexes were characterized by elemental analyses. IR spectra, TGDTA and magnetic property. Crystals(1) are triclinic, space group P1, a=0.92617(36), b=1.06973(17), c=1.08813(29) nm, a=59.60(2)°, β=74.83(3)°, γ=72.80(2)°, V=0.880 nm3, Dc = 1.520 g/cm3. Z=1, R=0.044, R,=0.048, Mr=805.78, 3477 reflections with I > 3o(I). Esch copper(II) ion is coordinated by two bridging bidentate benzoate ligands and one pyridine N-oxide or triphenylphosphine oxide to form dimeric binuclear molecules. The structure of the compound(1) shows a clear centre of symmetry.
