Ferromagnetic behavior at room temperature was observed in the tetramethylammonium (NMe4+) and cesium (Cs+) salts of tetracyanoquinodimethane (TCNQ) and its radical anion (TCNQ) in a molecular ratio of 1 : 2. The saturation magnetizations and coercive forces are 0.79 emu/mol and ≈ 300 Oe for (NMe4+ · TCNQ) · 1/2TCNQ, and 1.46 emu/mol and ≈ 100 Oe for (Cs+ · TCNQ) · 1/2TCNQ, respectively. In contrast, the 1 : 1 TCNQ/TCNQ mixed tetraethylammonium (NEt4+) salt, (NEt4+ · TCNQ) · TCNQ, exhibited no ferromagnetic behavior at room temperature nor at lower temperatures.
