N,N'-(Ethane-1,2-diyldi-o-phenyl-ene)bis-(pyridine-2-carboxamide).
The title mol-ecule, C(26)H(22)N(4)O(2), is centrosymmetric and adopts an anti conformation. Two intra-molecular hydrogen bonds, viz. amide-pyridine N-H⋯N and phen-yl-amide C-H⋯O, stabilize the trans conformation of the (pyridine-2-carboxamido)-phenyl group about the amide plane. In the crystal, the presence of weak inter-molecular C-H⋯O hydrogen bonds results in the formation of a three-dimensional network.
