A 1:1 composition organic conductor (TTM-TTP)I-3 has a highly one-dimension
al half-filled band, but shows a metallic conductivity down to 160 K. Anoth
er 1:1 composition organic conductor (TTM-TTP)[C(CN)(3)] has been prepared.
This compound has a one-dimensional column similar to the I-3(-) salt, but
the packing pattern of the columns is different. This compound exhibits a
metallic conductivity down to 70 K, an even lower temperature.
