Cyclohexadienyl radicals produced by γ-ray irradiation are thermally stable up to 423 K in the mother benzene clathrates Cd(en)Hg(CN)<SUB>4</SUB>·2C<SUB>6</SUB>H<SUB>6</SUB>, Cd(en)Cd(CN)<SUB>4</SUB>·2C<SUB>6</SUB>H<SUB>6</SUB>, Cd(tn)Hg(CN)<SUB>4</SUB>·2C<SUB>6</SUB>H<SUB>6</SUB>, and Cd(NH<SUB>3</SUB>)<SUB>2</SUB>Hg(CN)<SUB>4</SUB>· 2C<SUB>6</SUB>H<SUB>6</SUB>. However, no thermally stable C<SUB>6</SUB>H<SUB>7</SUB>· radicals have been observed in Cd(NH<SUB>3</SUB>)<SUB>2</SUB>Ni(CN)<SUB>4</SUB>· 2C<SUB>6</SUB>H<SUB>6</SUB> and Cd(en)Ni(CN)<SUB>4</SUB>·2C<SUB>6</SUB>H<SUB>6</SUB> even immediately after irradiation. The ESR spectra of C<SUB>6</SUB>H<SUB>7</SUB>· show the hyperfine splitting constants of the methylene, para, ortho, and meta protons 48, 13, 9, and 3 G, respectively.
