ELECTROPHORETIC STUDY OF CATIONIC COBALT(III) COMPLEXES WITH [N2O] AND [N2O2] SCHIFF-BASE LIGANDS

The electrophoretic migration behavior of acid-sensitive cationic alky lcobalt(III) complexes with tridentate Schiff bases and amines as well as that of related 'inorganic cobalt(III) chelates with tridentate an d tetradentate Schiff bases was studied. A correlation of the electrop horetic mobility of the organocobalt complexes in question with their structure was established. An attempt to optimize the analytical proce dures for capillary electrophoretic separation of these rather labile complex cations is outlined. Their decomposition in solutions under am bient conditions was surveyed using this technique. (C) 1998 Elsevier Science S.A. All rights reserved.
