چکیده

The title compound, 5-(4,5-dimethylthio-1,3-dithiol-2-ylidene)-1,3-diaza-2,4,6-trithiapentalene (4,5-dimethylthio [1,2,5]thiadiazolotetrathiafulvalene, molecular formula C(8)H(6)N(2)S(7)) crystallizes in the P2(1)/n space group with one molecule in the asymmetric unit. The molecular framework is planar within 0.19 A. The molecules form a head-to-tail type of pi-stacking dimer with an interplanar distance is 3.50(1) A, where methylthio groups face away from each other. The molecules are also linked by weak intermolecular S...S heteroatom interactions [3.497(1) and 3.572(1) A] to construct a unique one-dimensional molecular tape structure.

5-(1,3-Dithiolo[4,5-d][1,3]dithiol-2-yl­idene)-1,3-dithiolo[4,5-c][1,2,5]thia­diazole: an unsymmetrical tetra­thia­fulvalene with fused 1,2,5-thia­diazole and 1,3-dithiole rings

The title unsymmetrical tetra-thia-fulvalene (TTF), C(7)H(2)N(2)S(7), contains fused 1,2,5-thia-diazole and 1,3-dithiole rings and is a component mol-ecule for conducting organic solids. The TTF mol-ecule is disordered crystallographically over two orientations related by an inversion center, where each site is half-occupied. The mol-ecule is almost planar with an r.m.s. deviation of 0.096 Å. I...

Coordination-directed self-assembly of a simple benzothiadiazole-fused tetrathiafulvalene to low-bandgap metallogels.

Coordination-driven gelation of a benzothiadiazole-fused tetrathiafulvalene (TTF) is demonstrated. This is the first work reporting highly stable metallogels based on a donor-acceptor conjugate with such a simple structure for the construction of new low-bandgap materials with various functional properties and novel nanostructures.

Mono- and di-nuclear complexes of the ligands 3,4-di(2-pyridyl)- 1,2,5-oxadiazole and 3,4-di(2-pyridyl)-1,2,5-thiadiazole; new bridges allowing unusually strong metal–metal interactions

The syntheses of two new ligands, 3,4-di(2-pyridyl)-1,2,5-oxadiazole (dpo) and 3,4-di(2-pyridyl)-1,2,5-thiadiazole (dpt), are described. Complexes with palladium and copper have seven-membered chelate rings with coordination through the two pyridine nitrogens, whereas in the silver nitrate complex of dpt the ligand acts as a bridge between metal centres. Studies of the mononuclear ruthenium com...

Thiadiazoles: the appropriate pharmacological scaffolds with leishmanicidal and antimalarial activities: a review

Leishmaniasis and malaria are serious public health problems in tropical and sub-tropical regions worldwide. Development of drug-resistant strains has disrupted efforts to control the spread of these diseases in the world. The conventional antiparasitic chemotherapy still suffers from side effects and drug resistance. Therefore, the development of novel antimalarial and leishmanicidal drugs rem...
