DMTCA-BF4 (C = S, Se) have been considered as a quasi-one-dimensional half-filled system. For both salts, the structural two-fold modulation along the stacking direction was observed from room temperature. We also found a rapid decrease in spin susceptibility of DMTSA-BF4 below 100 K, but no anomaly at the metal-insulator transition temperature (150 K).
