Abstract
The reactions between the 16-electron complex (I) and several neutral, unsaturated N-heterocyclic ligands (II) are investigated in order to establish the nature of the paramagnetic cationic 17-electron complexes (III).
ChemInform Abstract
The reactions between the 16-electron complex (I) and several neutral, unsaturated N-heterocyclic ligands (II) are investigated in order to establish the nature of the paramagnetic cationic 17-electron complexes (III). These complexes exhibit room-temp. ESR signals in which hyperfine coupling to MO isotopes is apparent. The complexes with Py or N-methylimidazole as ligand exhibit a reversible one-electron reduction process in their cyclic voltammograms. However, where an exchangeable proton is bound to an N atom in L, irreversible reduction is observed. The neutral diamagnetic complex (V) (space group P1, Z=2) undergoes a reversible one-electron reduction at more anodic potentials than the complexes (III).
