Crystal Structure of the Radical-Cation Salt (o-Me2TTF)I-3 with Close Intermolecular Sulfur Contacts

摘要

The synthesis and crystal structure of the organic radical-cation salt (o-Me2TTF)I-3 is described. The salt crystallizes in the monoclinic space group P2(1) with a = 10.927(2) angstrom, b = 11.904(2) angstrom, c = 12.660(2) angstrom, beta = 115.174(5)degrees. The bond length of the central C=C bond in o-Me2TTF is 1.401(1) angstrom, indicating an approximate oxidation state of +1 for the o-Me2TTF radical cation.
