Abstract

Several new mononuclear copper(II) complexes, [Cu(phen)2L]PF6, where phen = 1,10-phenanthroline and L = monoanions of phenylcyanamide (pcyd), 2,5-dichlorophenylcyanamide (2,5-Cl2pcyd), 2-dichlorophenylcyanamide (2-Clpcyd) and 4-methylphenylcyanamide (4-Mepcyd), have been prepared and characterized by elemental analysis, UV–Vis, IR and 1H NMR spectroscopies and cyclic voltammetry. [Cu(phen)2(2,5-Cl2pcyd)]PF6 crystallized with a molecule of acetone with empirical formula of C31H20N6OF6Cl2PCu in a triclinic crystal system and space group P 1 with a = 9.2086(6) Å, b = 13.3117(9) Å, c = 15.5313(10) Å, α = 107.8210(10)°, β = 104.6180(10)°, γ = 104.1670(10)°, V = 1643.21(19) Å3 and Z = 2. The structure was refined using 7555 Mo-Kα reflections with I > 2σ(I) and R 1 = 0.0276 and Rw = 0.0692. The results are consistent with a mostly σ bonding interaction between Cu(II) and cyanamide anion. The LMCT band intensity and electrochemical potentials are compared with ruthenium phenylcyanamide analogues.
