The crystal structure contains two independent Cu(II) ions, with different geometry around each copper center, which are bridged by an acetate anion. The acetate-bridged ligand shows a syn-anti coordination mode with a trigonal bipyramidal geometry for the Cu(1) center and a distorted square-based pyramidal geometry for the Cu(2) center. The angular structural index parameter T for Cu(1) and Cu(2) is 0.9 and 0.33, respectively. The copper(II) atoms display a different geometry with a N(4)O chromophore group and with Cu-O distances of 1.993(5)-1.996(5) angstrom and Cu-N distances which vary from 1.980(5) to 2.161(6) angstrom. The intra Cu...Cu separation is 4.9904(5) angstrom. The effective magnetic moment (mu(eff)) of the complex was measured by the Evans method. The cyclic voltammogram of \Cu(phen)(2)\(2)(mu-CH(3)COO)PF(6)(3) shows two waves at positive potential which are assigned to the two Cu(II/I) reduction couples. (C) 2007 Elsevier Ltd.
