The enone group and the benzene rings of the title compound, C 16 H 13 NO 4 , are each planar. In the crystal structure, intermolecular C-HÁ Á ÁO interactions form chains along the a axis.
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 approximately planar molecule of the title compound, C 15 H 10 BrNO 3 , the dihedral angle between the two benzene rings is 4.97 (18) . Intermolecular C-HÁ Á ÁO interactions help to form chains of molecules in the crystal structure.
In the title compound, C~14~H~12~N~2~O~3~, the dihedral angle between the two aromatic rings is 86.13 (15)°. Intermolecular N—H...O hydrogen bonds [N...O = 2.886 (3) Å and N—H...O = 174 (3)°] between the NH~2~ and C=O groups link the molecules into a one-dimensional ribbon augmented by secondary N—H
