✦ Synopsis

The crystal structure of the title compound, C 10 H 6 Cl 3 NO 3 , establishes that condensation of 2,4,6-trichloroaniline with maleic anhydride gives the title compound at room temperature. There are strong intermolecular NÐHÁ Á ÁO hydrogen bonds [NÁ Á ÁO = 2.832 (2) and 2.867 (2) A Ê ], resulting in a hydrophobic region in the middle of the unit cell. The carboxyl groups adopt an anti-planar conformation and participate in intramolecular OÐHÁ Á ÁO hydrogen bonds [both OÁ Á ÁO = 2.486 (2) A Ê ]. There are two molecules in the asymmetric unit.

In the title molecule, C 15 H 9 BrClFO, the dihedral angle between the two benzene rings is 22.7 (1) . The crystal structure is stabilized by intermolecular C-HÁ Á ÁF interactions and short BrÁ Á ÁCl contacts [BrÁ Á ÁCl = 3.579 (1) A ˚]. The compound can potentially exhibit second-order nonlinear op
