The title compound, [Pd(CH(4)N(2)S)(4)](SCN)(2), consists of complex [Pd(TU)(4)](2+) [TU = thio-urea, SC(NH(2))(2)] cations and thio-cyanate counter-anions. The Pd(II) cation is situated on an inversion centre and exhibits an almost square-planar coordination by the S atoms of the TU ligands. The complex cations are connected through the thio-cyanate ions via N-H⋯N [2.922 (3)-3.056 (3) Å] and N...

The title compound, C(11)H(9)N(3)OS, was prepared to investigate the coordination chemistry of thio-phene-containing ligands as precursors to inter-esting metallopolymers. The mol-ecule is nearly planar. The angle between the thio-phene and pyridine rings is 8.63 (4)° and features the expected trans configuration about the imine bond. The structure is stabilized by a weak inter-molecular N-H⋯O ...

In the title compound, C(16)H(16)O(2)S, the central propenone group is almost planar (r.m.s. deviation = 0.009 Å) and subtends dihedral angles of 8.55 (8) and 16.22 (8)° to the 2-meth-oxy-phenyl and 2,5-dimethyl-thio-phene residues, respectively. The dihedral angle between the ring systems is 23.47 (5)°. In the crystal, mol-ecules are linked by weak C-H⋯π inter-actions and aromatic π-π stacking...

A series of new 6-amino-4aryl-2’-[(4-Aminophenyl)thio]-2,4’-bipyridine-5-carbonitriles (3a-h) were synthesized from 4-aminothiophenol (1). The reaction of 4-aminothiophenol with 4-acetyl-2-chloropyridine yielded 1-{2-[(4-aminophenyl)thio]pyridin-4-yl}ethanone(2).Furthertreatment of  2 with aromatic aldehydes in the presence of alcoholic malanonitrile in ammonium acetate gave compounds (3a-h). T...

The title compound, C9H7N3OS3·0.5H2O, crystallizes with two independent but similar mol-ecules in the asymmetric unit, both of which are linked by a water mol-ecule through O-H⋯N hydrogen bonds. In addition the water O atom is further linked by N-H⋯O hydrogen bonds to two additional main mol-ecules, forming a tetra-meric unit. These tetra-meric units then form infinite ribbons parallel to the a...

A series of thio-phenes substituted in positions 2 and 5 by imine groups have been synthesized using a solvent-free approach, and their crystal structures determined. The substituents are chiral groups, and the expected absolute configuration for each mol-ecule was confirmed by refinement of the Flack parameter. The compounds are 2,5-bis-[(S)-(+)-(1,2,3,4-tetra-hydro-naphthalen-1-yl)imino]-thio...

The title compound, C(12)H(16)N(2)O(2)S, was synthesized from furoyl isothio-cyanate and cyclo-hexyl-amine in dry acetone, and the crystal structure redetermined. The thio-urea group is in the thio-amide form. The structure [Otazo-Sánchez et al. (2001 ▶). J. Chem. Soc. Perkin Trans. 2, pp. 2211-2218] has been redetermined in order to establish the intra- and inter-molecular inter-actions. The t...

American trypanosomiasis, or Chagas' disease, is the leading cause of heart disease in Latin America. Currently there is an urgent need to develop antitrypanosomal therapy due to the toxicity of existing agents and emerging drug resistance. A novel series of potent thio semicarbazone small-molecule inhibitors of the Trypanosoma cruzi cysteine protease cruzain have been identified. Some of these...

The title compounds, C16H14O2S2 and C16H14O3S, which are monomeric models (models D and E) for a polythio-noester and a poly(ester-co-thio-noester), respectively, crystallize in the space group P21/c and are isostructural with each other. The mol-ecule in each crystal is located on an inversion centre and has an all-trans structure. The asymmetric unit comprises one half-mol-ecule. In the cryst...
