In the title compound, C7H8N4S2, the thio-phene ring shows rotational disorder over two orientations in a 0.6957 (15):0.3043 (15) ratio. The plane of the 1,2,4-triazole ring makes a dihedral angle of 75.02 (17)° with the major-disorder component of the thiophene ring. In the crystal, two types of inversion dimers, described by the graph-set motifs R22(8) and R22(10), are formed by N-H⋯S inter-a...

The reaction of thio-phene-3-carboxaldehyde and perfluoro-benzyl-triphenyl-phospho-nium bromide in the presence of sodium hydride gave the title compound, C(12)H(5)F(5)S, in 70% yield. The thiophene and perfluorophenyl groups form a dihedral angle of 5.4 (2)°. The structure is characterized by a head-to-tail organization in a columnar arrangement due to π-π inter-actions between the thio-phene ...

The title compound, C(8)H(2)Br(4)S(2), was prepared by bromination of 2,2'-bithio-phene with bromine. The mol-ecule is located on a crystallographic twofold rotation axis, thereby imposing equal geometry of the two thio-phene rings. Each five-membered ring is planar [maximum deviation 0.011 (9) Å] and the dihedral angle between the planes through the rings is 47.2 (4)°. The mol-ecules are arran...

In the centrosymmetric title compound, C(12)H(10)O(2)S(2), the alkyl chains adopt a fully extended all-trans conformation with respect to the C(thio-phene)-C bond. The non-H atoms of the mol-ecule are nearly planar, with a maximum deviation of 0.063 (2) Å from the mean plane of the constituent atoms. In the crystal, symmetry-related mol-ecules are linked via pairs of C-H⋯π contacts [H-centroid ...
