The title compound (PBT), C 14 H 14 N 4 S 4 , possesses C 2 symmetry, with the twofold axis bisecting the central benzene ring. The two terminal 2-(5-methyl-1,3,4-thiodiazolyl)thio groups adopt a trans conformation with respect to the benzene moiety, and the dihedral angle between the two thiodiazol

The title compound, C 10 H 14 N 2 S 4 , was synthesized by the reaction of the potassium salt of 2-thiothiazole and 1,4dibromobutane. The two 2-thiazolethio groups are related by a center of symmetry. The plane de®ned by the butyl carbon chain is approximately orthogonal to the thiazole plane, with
The asymmetric unit of the title compound, C 12 H 12 N 2 OS, contains two crystallographically independent molecules. Both molecules are essentially planar and stabilized by intraand intermolecular hydrogen-bonding interactions to form one-dimensional zigzag polymeric chains parallel to the c axis.
