4-Bromo-5-[(2-bromoethyl)sulfanyl]-1,3-dithiole-2-thione
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-molecu...
متن کاملThieno[3,4-d][1,3]dithiole-2-thione
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 t...
متن کاملEvidence for thiol-dependent production of oxygen radicals by 4-methyl-5-pyrazinyl-3H-1,2-dithiole-3-thione (oltipraz) and 3H-1,2-dithiole-3-thione: possible relevance to the anticarcinogenic properties of 1,2-dithiole-3-thiones.
1,2-Dithiole-3-thiones are an important class of anticarcinogens that selectively induce cellular production of chemoprotective phase II detoxification enzymes. It is important to identify chemical properties of anticarcinogens that are responsible for this enzyme induction. Previously, the ability of 1,2-dithiole-3-thiones to induce phase II enzymes has been attributed to their electrophilic c...
متن کامل5-Isopropylidene-1,3-dithiolo[4,5-d][1,3]dithiole-2-thione
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 کامل5-(4,5-Diiodo-1,3-dithiol-2-ylidene)-4′,5′-bis(methylsulfanyl)-2,2′-bi-1,3-dithiole-4(5H)-thione
The mol-ecular skeleton of the title mol-ecule, C(11)H(6)I(2)S(9), is nearly planar [maximum deviation 0.052 (3) Å] except for the two methyl groups. In the crystal, mol-ecules related by translation along b axis are associated into columns through π-π inter-actions between the five-membered rings, with a centroid-centroid distance of 3.593 (5) Å. Inter-action between adjacent columns is accomp...
