| Abstract: | A new approach to investigate the conformational properties of the Ni(II) complexes of maleic and succinic acids is reported. The use of C-13 and H-1 paramagnetic shifts and relaxation rates together with an INDO analysis on suitable radical models of the ligands proved a powerful tool in elucidating the conformation of the Ni(II) complex with the partially rigid maleic acid. |
