N,N′-Bis(4-hy­droxy­phen­yl)pyridine-2,6-dicarboxamide di­methyl­formamide monosolvate

The mol­ecular structure of the pyridine derivative, C(19)H(15)N(3)O(4)·C(3)H(7)NO, shows almost planar geometry with dihedral angles of 6.9 (1) and 13.4 (1)° between the pyridine ring and the two benzene rings. This conformation is stabilized by two intra­molecular N—H⋯N(pyridine) bonds. In the cry...

description The mol­ecular structure of the pyridine derivative, C(19)H(15)N(3)O(4)·C(3)H(7)NO, shows almost planar geometry with dihedral angles of 6.9 (1) and 13.4 (1)° between the pyridine ring and the two benzene rings. This conformation is stabilized by two intra­molecular N—H⋯N(pyridine) bonds. In the crystal, strong O—H⋯O(carboxamide) and N—H⋯O(hy­droxy­phen­yl) hydrogen bonds link the mol­ecules, forming a three-dimensional structure. The di­methyl­formamide solvent mol­ecules are not involved in the hydrogen bonding. The structure shows pseudosymmetry, but refinement in the space group Pbcn leads to significantly worse results and a disordered di­methyl­formamide mol­ecule.
