Abstract
The asymmetric unit of the title compound, C10H8N2·2C8H8O3, contains two 2-methoxybenzoic acid molecules and one 4,4′-bipyridine molecule. The 4,4′-bipyridine molecule is disordered over two positions in a 1:1 ratio. In the crystal, the 2-methoxybenzoic acid and 4,4′-bipyridine molecules are connected by intermolecular O—H⋯N hydrogen bonds. The dihedral angle between the carboxy group and its attached ring is 26.823 (2)°.
