Radical salts derived from TEMPO-substituted 2,4,6-triphenylpyridinium

Magnetic radical salts consisting of a TEMPO-substituted 2,4,6-triphenyl pyridinium with Ni(dmit)2, Pd(dmit)2 or Ni(mnt)2 counter anions have been prepared and the oxidized salts of the Ni(dmit)2 as well as Pd(dmit)2 complexes show semi-conducting properties with relatively high conductivities and low activation energies.
