N-(3-Chloro-phen-yl)-N'-(3-methyl-phen-yl)succinamide.

The asymmetric unit of the title compound, C(17)H(17)ClN(2)O(2), contains one half-mol-ecule with a center of inversion at the mid-point of the central C-C bond. The amide N-H group is anti to the meta-chloro/methyl groups in the adjacent benzene rings. The dihedral angle between the benzene ring and the NH-C(O)-CH(2) segment is 43.5 (1)°. In the crystal, inter-molecular N-H⋯O hydrogen bonds link the mol-ecules into chains along the a axis. The methyl group and the Cl atom occupy the same position and were treated in a disorder model with site-occupation factors of 0.5 each.
