Syntheses, crystal structures and density functional theoretical investigations of copper(II) complexes bearing tridentate Schiff base ligands derived from 8-aminoquinoline

Abstract

[eng] Three copperIJII) complexes, ijCuIJL1)IJH2O)IJOClO3)]n (1), ijCuIJL1)IJN3)] (2) and ijCuIJL2)IJCl)IJH2O)] (3) [HL1 = 4-chloro-2-IJ(quinolin-8-ylimino)methyl)phenol and HL2 = 2-ethoxy-6-IJ(quinolin-8-ylimino)methyl)phenol], have been synthesized and characterized by elemental analyses, IR and UV-Vis spectroscopy and singlecrystal X-ray diffraction studies. The theoretical study, carried out using density functional theory (DFT) calculations, is devoted to the analysis of the interesting supramolecular assemblies in the solid state of the structures, paying especial attention to lp -π and π-π interactions involving the quinolin-8-ylimino moiety
