✦ Synopsis

The electrochemical oxidation of anodic metals (iron and copper) in MeCN solutions of 2-pyridinone (HOPy), 1hydroxy-2-pyridinethione (HPT), 2-pyridinemethanethiol-1-oxide (HPMTO) or its dimer 2,2'-dithiodimethyldipyridine-l,l'-dioxide (PMTO)z, gave the simple complexes Fe(OPy)2" HzO, Cu(OPy)2" 3H20, Fe(PT)2" 3HzO, Ee(PT) 3, Cu(PT)2, Fe(PMTO):" 3H/O and Cu(PMTO)2" H20, respectively. When 1,10-phenanthroline (phen) was added to the electrolytic phase, only two mixed complexes were obtained: Cu(OPy)zphen'3H20 and Fe(PT)zphen'2H20. The possible molecular structures of the complexes were studied on the basis of their i.r. spectra and magnetic properties.
