2-(Octadecylsulfanyl)-1,3-thiazole

2,5-di-2-thienylthiazolo[4,5-d]thiazole.

The molecules of the title compound, C(12)H(6)N(2)S(4), lie on centres of symmetry. The thiophene and thiazole rings are almost planar and their planes make a dihedral angle of 1.68 (8) degrees. In the crystal structure, there is a relatively short intermolecular S...S contact distance of 3.5786 (9) A.

Ethyl 2-amino-4-tert-butyl-1,3-thiazole-5-carboxylate and 6-methylimidazo[2,1-b]thiazole-2-amino-1,3-thiazole (1/1).

The structure of ethyl 2-amino-4-tert-butyl-1,3-thiazole-5carboxylate, C10H16N2O2S, (I), and the structure of the 1:1 adduct 6-methylimidazo[2,1-b]thiazole±2-amino-1,3-thiazole (1/1), C6H6N2S C3H4N2S, (II), have been determined. The molecules in (I) associate via a hydrogen-bonded R2(8) dimer consisting of NÐH N interactions, with the hydrogenbonding array additionally involving NÐH O interacti...
