title: N,N'-Bis(2-methyl-phen-yl)succinamide.
abstract: In the title compound, C(18)H(20)N(2)O(2), the conformations of the N-H and C=O bonds in the C-NH-C(O)-C segments are anti to each other and the amide O atom is anti to the H atoms attached to the adjacent C atoms. Further, the conformations of the N-H bonds in the amide fragments are anti to the ortho-methyl groups in the adjacent benzene rings. The complete molecule is generated by inversion symmetry. The dihedral angle between the benzene ring and the NH-C(O)-CH(2) segment in the two halves of the mol-ecule is 62.1 (2)°. In the crystal, N-H⋯O inter-molecular hydrogen bonds link the mol-ecules into sheet-like infinite chains along the a axis.
