NEW MATERIAL:A TCNQ (tetracyanoquinodimethane) complex containing a nitrogen-containing heterocyclic compound cation, 7,7,8,8- tetracyanoquinodimethane anion radical (TCNQ-) and neutral TCNQ as constituent components. USE:An electrically conductive material. PREPARATION:The aimed substance is obtained by a method for reacting a nitrogen-containing heterocyclic compound cation iodide D+I- with neutral TCNQ at 3:4 molar ratio, reacting a halide of cation D+, e.g. a compound expressed by formulas I-IV, with Li salt of TCNQ to give D+TCNQ-, and doping the resultant D+TCNQ- with the neutral TCNQ, etc.
