Solvatochromism, DNA binding, antitumor activity and molecular modeling study of mixed-ligand copper(II) complexes containing the bulky ligand: Bis[N-(p-tolyl)imino]acenaphthene

Four mixed-ligand copper(II) complexes of the nitrogen ligand bis[N-(p-tolyl)imino]acenaphthene 1 (p-Tol-BIAN). These complexes, namely [Cu(p-Tol-BIAN)2](ClO4)22, [Cu(p-Tol-BIAN)(acac)](ClO4) 3, [Cu(p-Tol-BIAN)Cl2] 4 and [Cu(p-Tol-BIAN)(AcOH)2](ClO4)25, were prepared and characterized. Solvatochromism of the novel copper complexes in various solvents has been studied. Molecular mechanics (MM+) and molecular dynamic simulations have been performed to learn more about the solvatochromic behaviour and the DNA binding affinity of these complexes.
