چکیده
The title compound, C(5)H(4)Br(2)S(4), consists of a statistically planar, 4-bromo-1,3-dithiole-2-thione unit [maximum deviation from the ring plane 0.001 (2) Å], with a bromo-ethyl-sulfanyl substituent in the 5-position. In the crystal structure, weak inter-molecular S⋯S [3.438 (15) and 3.522 (15) Å] and S⋯Br [3.422 (14) and 3.498 (14) Å] inter-actions generate a three-dimensional supra-molecular architecture.

The title compound, C(7)H(6)S(5), contains a 5-yl-idene-1,3-dithiolo[4,5-d][1,3]dithiole-2-thione framework, which is an important synthetic precursor of multi-dimensional organic superconductors and conductors. The mol-ecular framework is planar with an r.m.s. deviation of 0.012 Å for the non-H atoms. In the crystal structure, mol-ecules are linked by short inter-molecular S⋯S inter-actions [3...
متن کاملHelical organization of chiral binaphthyl tetrathiafulvalene primary amides through hydrogen bonding interactions
Chiral tetrathiafulvalenes, (R) or (S), or racemic, (R,S), are obtained from a phosphite-mediated cross coupling reaction of a 1,3-dithiole-2-thione derivative bearing one binaphthol moiety, and are transformed into binaphthol-based tetrathiafulvalene ortho-diamides. The X-ray crystal structures of five intermediate chiral 1,3-dithiole-2-one and 1,3-dithiole-2-thione derivatives reveal the form...
