Synthesis, characterization and dissociation of mixed valent binuclear complexes
摘要:
Two mixed metal binuclear complexes, [(NH3)(5)Co-III (nta)Cu-II](2+) (1) and [(NH3)(5)Co-III(pyc)Cu-II](4+) (2; nta = nitrilotriacetate and pyc = pyridine-2-carboxylate) have been synthesized and characterized on the basis of elemental analysis; UV-vis, IR, ESR spectroscopy; magnetic and electrochemical measurements. A stopped flow kinetic study indicated that the dissociation of (NH3)(5)Co(nta)Cu2+ occured via spontaneous and acid catalysed paths. (C) 1997 Elsevier Science Ltd.
