title: 4-(2-Carboxy-benzo-yl)benzoic acid-4,4'-bipyridine (1/1).
abstract: In the heteromolecular title compound, C(15)H(10)O(5)·C(10)H(8)N(2), the two components are linked by O-H⋯N hydrogen bonds to form four-component ring supra-molecular assemblies. These are further inter-connected with neighbouring mol-ecules by weak inter-molecular C-H⋯π inter-actions and C-H⋯O hydrogen bonds to generate a three-dimensional network.
