| description | The asymmetric unit of the title compound, C19H11F3N2O2, contains two crystallographically unique molecules which differ in the rotation of a phenyl ring and a –CF3 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 CF3 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 (01-1). Crystallographically unique molecules alternate along the hydrogen-bonded chains. |
