1-Chloro-1-[(Z)-2-phenyl-hydrazin-1-yl-idene]propan-2-one.

ABSTRACT

The title compound, C(9)H(9)ClN(2)O, is close to planar (r.m.s. deviation for the non-H atoms = 0.0446 Å); it exists in a cis conformation with respect to the C=N double bond. In the crystal, the ketone O atom accepts both N-H⋯O and C-H⋯O hydrogen bonds, which leads to [010] infinite chains incorporating R(2) (1)(6) loops. The crystal structure also features a C-H⋯π inter-action.
