title: 2,2'-Bipyridine-cyclo-pentane-1,2,3,4-tetra-carb-oxy-lic acid (1/1).
abstract: The asymmetric unit of the title compound, C(10)H(8)N(2)·C(9)H(10)O(8), 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 mol-ecules 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.
