چکیده
In the title compound, C(5)H(2)S(4), the terminal monocyclic S atom deviates by 0.117 (1) Å from the mean plane of the other non-H atoms (r.m.s. deviation = 0.001 Å). All six C-S bonds and the central C-C bond in the rings are characterized by π-conjugated lengths, endowing the mol-ecule with high π-conjugation. In the crystal, the mol-ecules are parallel packed, forming columnar stacks along the a axis. Short inter-molecular S⋯S contacts [3.397 (1) and 3.486 (1) Å], are observed.

Helical 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...
متن کاملRedox-active tetrathiafulvalene and dithiolene compounds derived from allylic 1,4-diol rearrangement products of disubstituted 1,3-dithiole derivatives
We present a series of compounds by exploiting the unusual 1,4-aryl shift observed for electron-rich 1,3-dithiole-2-thione and tetrathiafulvalene (TTF) derivatives in the presence of perchloric acid. The mechanistic features of this rearrangement are discussed since this synthetic strategy provides an alternative route for the synthesis and functionalisation of sulfur rich compounds including r...

The mol-ecule of the title compound, C(7)H(6)N(2)S(3), is almost planar, the dihedral angle between the benzene plane and the 1,3-dithiole-2-thione plane being 2.21 (6)°. In the crystal, mol-ecules are linked by inter-molecular N-H⋯S and N-H⋯N hydrogen bonds into a three-dimensional network. The crystal packing also exhibits weak inter-molecular S⋯S inter-actions [3.5681 (9) Å].

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...
