Synthesis, structure and properties of the new tetracyanoquinodimethane anion-radical salt (ARS) having the composition (N-Et-2.5-di-Me-Pz)(TCNQ)₂ (Pz is pyrazine) are reported. The compound has a layered structure where conducting anion-radical layers formed by TCNQ alternate with non-conducting cation layers along the a axis. The charges of TCNQ particles in the stack alternate, i.e. are localized appreciably, which can account for a rather unusual temperature dependence of electric resistance. Such a peculiarity of structure renders to the ARS electronic system a somewhat two-dimensional character that is unusual for TCNQ ARS and agrees with the electrophysical measurements.
