The molecules of the title compound, C 14 H 11 BrO 2 S, display some distorted geometrical values that may be ascribed to an HÁ Á ÁBr close contact. In the crystal structure, the molecules form translation-symmetry-generated infinite chains by way of a C-HÁ Á ÁO interaction.

The title compound, C~17~H~17~BrO~2~S, forms centrosymmetric dimers linked by weak C—H...O hydrogen bonding generating an __R__ ^2^(10) ring. The dihedral angle between the thienyl and benzene rings is 5.79 (10)°.

The title compound, C 15 H 14 BrNOS, crystallizes with two molecules in the asymmetric unit. One of the two molecules forms dimers held together by weak C-HÁ Á ÁO interactions. The twist angles between the thienyl and benzene rings are 2.70 ( 16) and 4.76 (18) , smaller than usually observed in chal
