In this study, two copper(II) complexes, [CuL1Cl2] (1) and [CuL2Cl2] (2), and two copper(II)−platinum(II) heteronuclear complexes, [CuPtL1(DMSO)Cl4] (3) and [CuPtL2(DMSO)Cl4] (4), were synthesized using two bifunctional ligands, N-[4-(2-pyridylmethoxy)benzyl]-N,N-bis(2-pyridylmethyl)amine (L1) and N-[3-(2-pyridylmethoxy)benzyl]-N,N-bis(2-pyridylmethyl)amine (L2). These complexes have been characterized
