2,2′-Bipyridine–cyclopentane-1,2,3,4-tetracarboxylic acid (1/1)

Abstract

The asymmetric unit of the title compound, C10H8N2·C9H10O8, contains a half-molecule of 2,2′-bipyridine and a half-molecule of 1,2,3,4-cyclopentanetetracarboxylic acid, both components being completed by crystallographic inversion symmetry. In the crystal, the molecules are assembled into chains extending along [010] by O—H...N hydrogen bonds; adjacent chains are linked by O—H...O hydrogen bonds into a three-dimensional network.
