چکیده
The asymmetric unit of the the title compound, C(7)H(7)ClN(2)O, contains two mol-ecules in which the chloro-phenyl and the formic hydrazide units are almost planar (r.m.s. deviations of 0.0081 and 0.0100 Å, respectively, in one mol-ecule and 0.0069 and 0.0150 Å in the other) and are oriented with respect to each other at dihedral angles of 56.8 (2) and 56.9 (2)°. In the crystal, the mol-ecules are consolidated in the form of polymeric chains extending along [010]. R(3) (3)(10) ring motifs exist due to N-H⋯O and N-H⋯N hydrogen bonds.
