Crystal structure and Hirshfeld-surface analysis of a monoclinic polymorph of 2-amino-5-chloro­benzo­phenone oxime at 90 K

The synthesis and crystal structure of a monoclinic polymorph of 2-amino-5-chloro­benzo­phenone oxime, C(13)H(11)ClN(2)O, 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 8...

Sumario:The synthesis and crystal structure of a monoclinic polymorph of 2-amino-5-chloro­benzo­phenone oxime, C(13)H(11)ClN(2)O, 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.
