Abstract
The mono(dpa)copper(II) complex [Cu(dpa)Cl2] (1) (dpa = di-(2-picolyl)amine) has been synthesized and structurally characterized. It crystallizes in the monoclinic system P21/n with a = 8.155(1), b = 12.560(1), c = 12.817(2) A, β = 91.64(2)°, V = 1312.3(2) A3, Z = 4. The copper atom is coordinated by three nitrogen atoms from the dpa ligand and two chlorides in a distorted square-pyramidal environment. Cyclic voltammetric data show that 1 undergoes the reversible one-electron oxidation to the Cu(III) and the reversible one-electron reduction to the Cu(I) state.
