New non-conjugated functionalized 2,5-dihydroimidazole-type bi- and trinitroxyl radicals are described. The synthesis of which was based on a nucleophilic substitution reaction between 2,4,6-trichloro-1,3,5-triazine or 2,4-dichloro-6-methoxy-1,3,5-triazine and spiro-fused 2,5-dihydroimidazole-type monoradicals bearing both a p-hydroxyaryl moiety at the C-4 atom of the heterocycle and a residue at the fourth position of the cyclohexane ring. The model tris-nitroxide with an unsubstituted cyclohexane unit was structurally characterized in the solid state.
