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

ABSTRACT: The asymmetric unit of the title compound, C(19)H(11)F(3)N(2)O(2), contains two crystallographically unique mol-ecules 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 mol-ecule, there is a close contact between an H atom and the centroid of the phenyl ring of an adjacent mol-ecule (2.572?Å). A similar contact is lacking in the second mol-ecule. In the crystal, N-H?O inter-actions connect adjacent mol-ecules into a chain normal to (01[Formula: see text]). Crystallographically unique mol-ecules alternate along the hydrogen-bonded chains.
