Naphthalene-1,4,5,8-tetracarboxylic acid 1,8-anhydride–4,4′-bipyridine (1/1)

Abstract

The title compound, C14H6O7·C10H8N2, has been hydrothermally synthesized. Structural ananlysis indicates that the crystals are produced by cocrystallization of naphthalene-1,4,5,8-tetracarboxylic acid 1,8-anhydride and 4,4′-bipyridine (bpy) molecules. The crystal packing is stabilized by intermolecular O—H...N and C—H...O hydrogen bonds and π–π stacking interactions [centroid–centroid distances = 3.5846 (9) Å].
