Influence of meridional N3-ligands on supramolecular assembling and redox behavior of carboxylatocopper(II) complexes
摘要:
Mononuclear phenylglyoxylato- and 4-R-benzoatocopper(II) complexes with two different 1,3-bis(2-arylimino) isoindoline ligands (aryl = pyridyl, or benzimidazolyl) have been synthesized and characterized. Coordination mode of the carboxylate ligands is very similar (monodentate) in each case, while redox behavior of the copper center is dependent on the aryl- and 4-R-substituents. The supramolecular assembly in the solid state via hydrogen bonds and pi-stacking between the ligands can be influenced by the aryl-group and carboxylate ligand. (C) 2011 Elsevier B.V.
