Structure of 2-chloro--(-tol-yl)propanamide.

Two independent samples of the title compound, alternatively 2-chloro--(4-methylphenyl)prop-an-amide, CHClNO, , were studied using Cu α, , and Mo α, , radiation as part of a continuous crystallization study. The mol-ecule crystallizes with disorder in the Cl/terminal methyl positions [occupancies for the major disorder component of 0.783 (2) in and and 0.768 (2) in ] and exhibits N-C bond lengths of 1.3448 (19), 1.344 (2) Å, C=O bond lengths of 1.2233 (18) and 1.2245 (19) Å and an acetamide moiety C-N-C-C torsion angle of 179.00 (13), 178.97 (14) ° for and , respectively. In the crystal, chains along the axis are formed N-H⋯O hydrogen bonds between acetamide groups, as well as C-H⋯O inter-actions. These chains arrange themselves into parallel running stacks which display weak C-Cl⋯O=C halogen bonding as well as weak C-H⋯π inter-actions.
