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(C 5 H 5 NO)‐(C 6 H 5 COO) 2 ]2(1), [Cu(OPPh 3 )(C 6 H 5 COO)2]2(2) and [Cu(C 6 H 5 COO)(C 26 H 20 N 2 )](3, C 26 H 20 N 2 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 nm 3 , D c = 1.520 g/cm 3 . 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.
