title: N-(3,4-Dichloro-phen-yl)-3-oxo-butanamide.
abstract: In the title compound. C(10)H(9)Cl(2)NO(2), the acetamide residue is twisted out of the phenyl ring plane by 25.40 (9)°. An intra-molecular C-H⋯O close contact is observed. The N atom of the butanamide unit forms an inter-molecular N-H⋯O hydrogen bond with the symmetry-related carbonyl O atom, inter-linking mol-ecules into a C(4) chain along [100]. Additional C-H⋯O inter-molecular inter-actions and Cl⋯Cl contacts [3.4364 (8) Å] contribute to the stability of the crystal packing.
