4,4′-Bipyridyl–2-chloro-4-nitrobenzoic acid (1/2)

Abstract

In the crystal structure of the title 1:2 cocrystal, C10H8N2·2C7H4ClNO4, the two components are held together by short O—H...N hydrogen bonds. The pyridine rings of the bipyridyl molecule are twisted by 27.90 (5)° with respect to each other. The 1:2 units are connected by C—H...O hydrogen bonds, forming a centrosymmetric supramolecular ring.
