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

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

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&#82...
