2,4-Diphenyl-6-trifluoro­methyl-2,3-dihydro-1H,5H-pyrrolo­[3,4-c]pyrrole-1,3-dione

The asymmetric unit of the title compound, C(19)H(11)F(3)N(2)O(2), contains two crystallographically unique mol­ecules which differ in the rotation of a phenyl ring and a –CF(3) substituent. The dihedral angles involving the pyrrole ring and the attached phenyl ring are 62.82 (8) and 71.54 (7)° in the two molecules. The difference in the rotation of the CF(3) groups with respect to the pyrrolo rings to which they are attached is 23.5(1)°. For one mol­ecule, there is a close contact between an H atom and the centroid of the phenyl ring of an adjacent mol­ecule (2.572 Å). A similar contact is lacking in the second mol­ecule. In the crystal, N—H⋯O inter­actions connect adjacent mol­ecules into a chain normal to (01[Image: see text]). Crystallographically unique mol­ecules alternate along the hydrogen-bonded chains.
