The dihedral angle between the triazole and thiophene rings is 4.83 (14)° while those between the triazole and toluyl rings and between the thiophene and phenyl rings are 48.42 (16) and 9.23 (13)°, respectively. An intramolecular N—H⋯O hydrogen bond closes an S(6) loop. In the crystal, molecules are stacked parallel to the a-axis direction with weak π–π interactions between adjacent thiophenyl and triazolyl groups within the stack.

All of the atoms except the C—H groups in the bromobenene ring lie on a (010) crystallographic mirror plane, with the benzene ring completed by reflection. The dihedral angle between the ring systems is constrained to be 90° by symmetry. In the crystal, molecules are linked by weak C—H⋯Br interactions in the [100] direction and paired very weak C—H⋯O interactions to the same acceptor in the [001] direction, generating (010) sheets.
