    dct:description """
              Two anilinosalen and a mixed phenol-anilinosalen ligands involving sterically hindered anilines moieties were synthesized. Their nickel(II) complexes <b>1</b>, <b>2</b>, and <b>3</b> were prepared and characterized. They could be readily one-electron oxidized (<i>E</i><sub>1/2</sub>=-0.30, -0.26 and 0.10V vs. Fc<sup>+</sup>/Fc, respectively) into anilinyl radicals species <b>[1]</b><sup>+</sup>, <b>[2]</b><sup>+</sup>, and <b>[3]</b><sup>+</sup>, respectively. The radical complexes are extremely stable and were isolated as single crystals. X-ray crystallographic structures reveal that the changes in bond length resulting from oxidation do not exceed 0.02Å within the ligand framework in the symmetrical <b>[1]</b><sup>+</sup> and <b>[2]</b><sup>+</sup>. No quinoid bond pattern was present. In contrast, larger structural rearrangements were evidenced for the unsymmetrical <b>[3]</b><sup>+</sup>, with shortening of one C<sub>ortho</sub>-C<sub>meta</sub> bond. Radical species <b>[1]</b><sup>+</sup> and <b>[2]</b><sup>+</sup> exhibit a strong absorption band at around 6000cm<sup>-1</sup> (class III mixed valence compounds). This band is significantly less intense than <b>[3]</b><sup>+</sup>, consistent with a rather localized anilinyl radical character, and thus a classification of this species as class II mixed-valence compound. Magnetic and electronic properties, as well as structural parameters, have been computed by DFT methods.
