Hydrogen-bonded dimers of 1 (a) and 2 (b) in the crystal. Displacement ellipsoids are drawn at the 50% probability level. The site of the disordered trifluoromethyl group in 2 with minor occupancy (ca 12%) in the crystal is shown by empty ellipsoids. Hydrogen atoms are represented by small spheres of arbitrary radius and hydrogen bonds are shown by dashed lines. Symmetry code: (i) −x + 2, −y + 1, −z + 1.
