N,N'-Diethyl-N,N'-diphenyl-pyridine-2,6-dicarboxamide.

ABSTRACT: The asymmetric unit of the title compound, C(23)H(23)N(3)O(2), contains two mol-ecules in both of which, one amide N atom is in a syn position with respect to the pyridine N atom, while the other amide N atom is in an anti position (the syn--anti conformation). There are minor conformational differences between the two mol-ecules, as reflected in the N(pyridine)-C-C-N(amide) torsion angles of -44.9?(3) and 136.0?(2)° for one mol-ecule and 43.5?(3) and -131.1?(2)° for the other mol-ecule. However, the two mol-ecules show significant differences in the orientation of an ethyl group, with corresponding C-C-N-C torsion angles of 86.6?(3)° for one mol-ecule and 79.6?(3)° for the other mol-ecule. In the crystal, mol-ecules are linked by weak C-H?O hydrogen bonds, forming a three-dimensional supra-molecular network.
