DIRECT ELECTROCHEMICAL SYNTHESIS AND CHARACTERIZATION OF COPPER(II), IRON(II) AND IRON(III) COMPLEXES WITH 1-SUBSTITUTED AND 2-SUBSTITUTED PYRIDINES

The electrochemical oxidation of anodic metals (iron and copper) in Me CN solutions of 2-pyridinone (HOPy), 1-hydroxy-2-pyridinethione (HPT), 2-pyridinemethanethiol-1-oxide (HPMTO) or its dimer 2,2'-dithiodimeth yldipyridine-1,1'-dioxide (PMTO)2, gave the simple complexes Fe(OPy)2. H2O, Cu(OPy)2.3H2O, Fe(PT)2.3H2O, Fe(PT)3, Cu(PT)2, Fe(PMTO)2.3H2O and Cu(PMTO)2.H2O, respectively. When 1,10-phenanthroline (phen) was adde d to the electrolytic phase, only two mixed complexes were obtained: C u(OPy)2phen.3H2O and Fe(PT)2phen.2H2O. The possible molecular structur es of the complexes were studied on the basis of their i.r. spectra an d magnetic properties.
