Abstract

The synthesis and crystal structure of a monoclinic polymorph of 2-amino-5-chloro­benzo­phenone oxime, C13H11ClN2O, are presented. The mol­ecular conformation results from twisting of the phenyl and 2-amino-5-chloro benzene rings attached to the oxime group, which subtend a dihedral angle of 80.53 (4)°. In the crystal, centrosymmetric dimers are formed as a result of pairs of strong O - H⋯N hydrogen bonds. A comparison is made to a previously known triclinic polymorph, including differences in atom-atom contacts obtained via a Hirshfeld-surface analysis.
