A nitronyl nitroxide unit (NN) was linked with a triphenylamine‐based condensed polycyclic skeleton DOTT to form a radical substituted donor NN‐DOTT. X‐ray crystal structure analysis demonstrated a flat bowl shape of the DOTT unit. EPR spectra showed the localization of electron spin on the NN unit. Chemical oxidation of the DOTT unit produced radical‐substituted radical cation salts NN‐DOTT⁺ ⋅ SbF₆⁻ and NN‐DOTT⁺ ⋅ FeBr₄⁻ that are stable under ambient conditions. The magnetic behavior of NN‐DOTT⁺ ⋅ SbF₆⁻ is characterized by the strong intramolecular ferromagnetic interaction between NN and DOTT⁺. The X‐ray structural analysis of NN‐DOTT⁺ ⋅ FeBr₄⁻ shows planar structure of DOTT and 1D mixed‐stack column of NN‐DOTT⁺ and FeBr₄⁻. Magnetic measurements established that NN‐DOTT⁺ ⋅ FeBr₄⁻ undergoes magnetic phase transition into a weak ferromagnet at 7 K.
