SYNTHESIS, CHARACTERIZATION AND THE CRYSTAL-STRUCTURE OF DICOPPER COMPLEX [CU-2(C6H4COO)(4)(C8H1-1N)(2)]

Dibenzoyl peroxide undergoes oxidative addition to metallic copper wit h 2,4,6-trimethylpyridine in acetone solvent and affords the binuclear complex [Cu-2(C6H5COO)(4)(C8H11N)(2)]. This complex has been characte rized by elemental analysis, IR and UV-vis spectroscopies, thermal ana lysis and X-ray diffraction techniques. The X-ray studies show that th e structure of the complex is monoclinic, space group, P2(1)/N, with c ell parameters, a=10.499(4), b=10.666(6), c=18.109(3) Angstrom, beta=9 2.92(2)degrees, V=2025.2 Angstrom(3) Z=2, Dc=1.398g.cm(-3), R=0.068 an d Rw=0.075. Each copper ion is coordinated by four bridging bidentate benzoate ligands and one 2,4,6-trimethylpyridine to form binuclear mol ecule.
