Description	721-722 Dibenzoyl peroxide undergoes oxidative addition on metallic copper powder with imidazole (C<sub>3</sub>H<sub>4</sub>N<sub>2</sub>) in a mixed solvent (ethanol, methanol and tetrahydrofuran) and affords the complex [Cu(C<sub>3</sub>H<sub>4</sub>N<sub>2</sub>)<sub>2</sub>(C<sub>6</sub>H<sub>5</sub>COO)<sub>2</sub>]. The X-ray 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 0.033 for 1417 independent reflection of <em>I</em>>3σ(<em>I</em>)<em>. The crystals are monoclinic, C<sub>20</sub>H<sub>18</sub>N<sub>4</sub>O<sub>4</sub>Cu, MR=441.74, space group P2(1)/<em>n,</em> with cell parameters <em>a</em> = 8.699(4); <em>b</em> = 9.540(6); <em>c</em> = 12.399(5)Ǻ; ɑ = γ = 90°; β = 100.8 °; <em>V</em> = 1010.0Ǻ<sup>3</sup>; Dc = 1654 g.cm<sup>-3</sup>; μ = 21.4 cm<sup>-1</sup> and Z = 4. Each copper ion is coordinated by two benzoate and two imidazole ligands. The structure of the title compound shows a clear centre of symmetry.
