2-(2,4-Dichlorophenoxy)-1-(1H-pyrazol-1-yl)ethanone

Abstract

In the title compound, C11H8Cl2N2O2, the 2,4-dichlorophenoxy and 1H-pyrazole groups are almost planar [r.m.s. deviations of 0.0157 and 0.0008 Å, respectively] and are oriented at a dihedral angle of 64.17 (5)° with respect to one another. In the crystal, the molecules are stabilized in the form of dimers due to inversion-related C—H...O hydrogen bonds, with R22(10) ring motifs.
