At room temperature, dibenzoyl peroxide undergoes oxidative addition reaction with metallic copper powder and 4-dimethylamine-pyridine which affords the last products as binuclear copper (Ⅱ) complex (1),[Cu(C6H5COO)2(C7H10N2)]2. This complex is further characterized by spectroscopic methods. The structure of complex (1) has been determined by a single-crystal X-ray analysis. Crystallographic data are as follows: monoclinic, space group P21, a = 10. 446(2)A, b = 11. 140(5)A, c = 17. 179(3)A, β=95.92(3)°, V= 1988.4(7) A3, Z=4, F(000) =884, μ=11.27cm-1, D(calcd.) =1.429g@cm-3, R=0.0399, Rw=0. 1202. Each copper (Ⅱ) ion is coordinated by two bridging bidentate benzoate and 4-dimethylamine-pyridine to form dimeric molecule. CCDC: 188744.
