N,N′-Bis(pyridin-3-yl)terephthalamide-terephthalic acid (1/1)

Abstract

In the title compound, C18H14N4O 2·C8H6O4, both types of mol-ecule lie on inversion centers. In the N,N′-bis-(pyridin-3-yl) terephthalamide mol-ecule, the pyridine ring forms a dihedral angle of 11.33 (9)° with the central benzene ring. In the crystal, N - H⋯O and O - H⋯N hydrogen bonds connect the components into a three-dimensional network. © Lu et al. 2011.
