Abstract:
The molecule of the title compound, C(12)H(8)ClF(3)N(4)O, is twisted as indicated by the C-O-C-C torsion angle of 76.9 (3)°. Moreover, the trifluoro-methyl group shows rotational disorder of the F atoms, with site-occupancy factors of 0.653 (6) and 0.347 (6). The dihedral angle between the rings is 1.88 (12) Å.
