The geometrical parameters for the title compound, C 16 H 13 NO 2 S, are normal. The non-centrosymmetric crystal packing, which is consistent with the non-zero second harmonic generation response, may be influenced by a weak intermolecular C-HÁ Á ÁO interaction.

In the title compound, C 12 H 9 BrClN 3 O 3 , the nitro group lies in the plane of the imidazole ring, whereas the benzene and acetyl groups are markedly twisted relative to the heterocyclic ring. A weak C-HÁ Á ÁO interaction helps to establish the crystal packing.
In the title compound, C~28~H~22~BrN~3~O~5~S·0.5C~4~H~10~O, the tetrahydropyrazine ring adopts a distorted half-chair conformation. The bromobenzaldehyde substituent has an axial orientation, while the 4-nitrophenyl group is in an equatorial position. The benzene rings of these substituents are not
