In 1, the copper(II) ion has a distorted square-pyramidal geometry with three nitrogen atoms of the dpa ligand and two oxygen atoms of the nitrate anions. The crystal structure of 2 shows that the copper(II) ions are bridged by tp anion to form a dinuclear complex, in which each copper(II) ion exhibits a distorted square-pyramid with three nitrogen atoms of the dpa ligand, water molecule, and the oxygen atom of the bridging tp ligand. Cyclic voltammetric data indicate that 1 undergoes irreversible one-electron oxidation to the CuIII and reversible one-electron reduction to the CuI, while 2 gives one reversible oxidation and two reversible and irreversible reduced processes. The electronic spectra and redox potentials of the complexes are influenced significantly by the anionic ligands. Graphical Abstract: The reaction of [Cu(dpa)Cl2] with K(NO3)2 and Na2tp yields mononuclear and dinuclear copper(II) complexes [Cu(dpa)(NO3)2] (1) and [Cu2(dpa)2(H2O)2(μ-tp)](tp)·6H2O (2) (dpa=di-(2-picolyl)amine, tp=terephthalate).
