Crystal structure of cyproconazole

Abstract

The title compound [systematic name: 2-(4-chlorophenyl)-3-cyclopropyl-1-(1H-1,2,4-triazol-1-yl)butan-2-ol], C15H18ClN3O, is a conazole fungicide. The asymmetric unit comprises two enantiomeric pairs (molecules A and B) in which the dihedral angles between the chlorophenyl and triazole rings are 46.54 (9) (molecule A) and 67.03 (8)° (molecule B). In the crystal, C—H...O, O—H...N and C—H...Cl hydrogen bonds and weak C—H...π interactions [3.473 (2) Å] link adjacent molecules, forming columns along the a axis.
