Electrical resistance temperature dependence of three TCNQ anion-radical salts of complex composition containing cations [M||(bipy)₃]²⁺ (M-Fe, Ni or Zn, bipy - 2,2′-dipyridil) have been studied. Measurements have been performed in the range 180-300 K on tableted samples. The compound exhibit semiconducting properties and undergo the Peierls transition. Specific resistance at room temperature is of 7.7 Ω·cm for Fe containing salt and 2.3·10⁻² Ω·cm and 2.5·10⁻² Ω·cm for salts containing Ni and Zn, respectively.
