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

G. Waris, H. M. Siddiqi, U. Flörke, R. Hussain and M. S. Butt

Abstract: The molecular structure of the pyridine derivative, C19H15N3O4·C3H7NO, 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.
