Copper(II) complexes of 2-(pyrrolidinomethyl)- and 2-(3-pyrrolinomethyl)pyridine N-oxides

Summary This title pyridine N-oxides have been prepared and their copper(II) complexes isolated as perchlorate, tetrafluoroborate and nitrate salts. The ligands coordinatevia both the pyridine N-oxide oxygen and the amine nitrogen to give bis(ligand) complexes for the perchlorate and tetrafluoroborate salts. The nitrate solids have CuL(NO₃)₂] stoichiometry with monodentate nitrato-ligands. The spectral properties of these complexes are compared to those of N-alkyl-and N,N-dialkyl2-picolinamine N-oxides as well as other 2-substituted pyridine N-oxides.NATO Fellow on leave from Istanbul Medical Faculty, Istanbul University.
