Antiperovskite Structure with Ternary Tetrathiafulvalenium Salts: Construction, Distortion, and Antiferromagnetic Ordering

View publication


Rhombohedral distortion caused by the shape of the organic ions is found in the antiperovskite structures of all four ternary salts 1,which were obtained by electrocrystallization of the components tetrathiafulvalene (TTF),tetrabutylammonium halohexamolybdate, and tetrabutylammonium halide. The three‐fold symmetry is quite apparent in the structural representation of these salts on the right. These salts show a sharp transition to an antiferromagnetic ground state between 6 and 8 K.
