Abstract Mixed-ligand NiIII complexes with α-nitroso-β-naphthol, β-nitroso-α-naphthol,o-ethylxanthate, andN,N-diethyldithiocarbamate as ligands have been studied by ESR in liquid and frozen solutions. The degrees of symmetry distortion for the first coordination sphere of these complexes have been determined. It is shown that the transition from planar square NiIIL2 complexes to more stable octahedral NiIIIL2L′ and NiIIILL2′ complexes occursvia the radical addition mechanism. A method for trapping short-lived radicals is suggested on the basis of the complex formation scheme.
