H-bonded supramolecular assembly via proton transfer: Isolation, X-ray crystallographic characterization and SOD mimic activity of [Cu(dipic) 2 ] 2 [PA-H] 4 ·5H 2 O
The title proton transfer complex was isolated from the reaction of CuCl 2 ·2H 2 O with pyridine-2,6-dicarboxylic acid (dipic-H 2 ) in presence of 3-amino-1-propanol (PA) under reflux condition. It was thoroughly characterized by FAB-mass, FT-IR, electronic (ligand field), EPR spectroscopic and X-ra...
