N-(2-Chloro-phen-yl)-N'-(2-methyl-phen-yl)succinamide.

ABSTRACT: In the title compound, C(17)H(17)ClN(2)O(2), the asymmetric unit contains half a mol-ecule with a centre of symmetry at the mid-point of the central C-C bond. The conformations of the amide O atoms are anti to the methyl-ene atoms. Further, the N-H bonds in the amide fragments are anti to the ortho-chloro/methyl groups in the adjacent benzene rings. The dihedral angle between the benzene ring and the NH-C(O)-CH(2) segment in the two halves of the mol-ecule is 62.0?(2)°. In the crystal, a series of N-H?O inter-molecular hydrogen bonds link the mol-ecules into column-like infinite chains along the a axis. The methyl and Cl groups are disordered with respect to the ortho positions of the benzene ring, with site-occupation factors of 0.5 each.
