4-(4-Chloro-5-methyl-3-trifluoromethyl-1H-pyrazol-1-yl)-6-(prop-2-ynyloxy)pyrimidine

Abstract

Key indicators: single-crystal X-ray study; T = 173 K; mean (C-C) = 0.003 Å; disorder in main residue; R factor = 0.044; wR factor = 0.106; data-to-parameter ratio = 10.7.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 trifluoromethyl 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 .
