Ethyl 2-[(4-chloro-phen-yl)hydrazono]-3-oxobutanoate.

ABSTRACT: The mol-ecule of the title oxobutanoate derivative, C(12)H(13)ClN(2)O(3), is nearly planar; the inter-planar angle between the benzene ring and the mean plane through the hydrazono-3-oxobutanoate unit is 2.69?(3)°. An intra-molecular N-H?O hydrogen bond generates an S(6) ring motif. In the crystal packing, C-H?O(3-oxo) inter-actions link mol-ecules into dimers. The dimers thus formed are linked through C-H?O(carboxyl-ate C=O) inter-actions, leading to the formation of ribbons along the [01] direction, which are stabilized via Cl?Cl [3.2916?(3)?Å] contacts. The ribbons are stacked via C?O contacts [3.2367?(12)-3.3948?(12)?Å].
