The complex of Cu(tpy)(phen-dione)(PF6)(2) Crystallized with one molecule of acetonitrile. The ORTEP drawing of Cu(tpy)(phen-dione)(PF6)(2)center dot CH3CN shows that the coordination geometry around Cu-II is a distorted trigonal-bipyramid. Due to the steric hindrance of PF6- in the unit cell, the tpy ligands in each complex cation cannot interact in a pi-pi fashion. The effective magnetic moment (mu(eff)) of the complexes was measured by the Evans method. The cyclic voltammograms at Pt disk electrode for these complexes display only one reversible Cu(II)/Cu(I) redox couple. (C) 2007 Elsevier B.V. All rights reserved.
