Synthesis and structure of copper(II) complex [Cu(C5H5N)(2)(H2O) (C6H5COO)(2)]

At room temperature, the reaction of dibenzoyl peroxide with metallic coppe r powder in the presence of pyridine affords the copper(II) complex [Cu(C5H 5N)(2) (H2O)-(C6H5COO)(2)]. Crystal is monoclinic, M-r = 483.002, space gro up Cc with parameters: a = 6.078(4), b = 15.879(4), c = 23.091(3) Angstrom, beta = 97.61(2)degrees, V = 2209.1(2) Angstrom (3), Z = 4, D-c = 1.464g/cm (3), mu = 10.279 cm(-1), F(000) = 996,. R = 0.031, R-w = 0.036, 1595 reflec tions with I greater than or equal to 3 sigma (I) were considered to be obs erved. Each copper( II) ion is coordinated by two monodentate benzoate liga nds, two pyridines and one water molecule. The complex is also characterize d by its IR, XPS and thermal properties.
