【 摘 要 】

The asymmetric unit of the title 1:1 co-crystal, C10H8N2·C10H10O4, consists of one half-molecule each of 4,4′-bipyridine and 1,4-phenylenediacetic acid: the complete molecules are generated by crystallographic inversion centres. The dihedral angle between the –CO2H group and the benzene ring in the diacid is 73.02 (7)°. In the crystal, the components are linked by O—H...N hydrogen bonds, generating [1-2-1] chains of alternating amine and carboxylic acid molecules. The chains are cross-linked by C—H...O interactions. This structure was previously incorrectly described as a (C10H10N2)2+·(C10H8O4)2− molecular salt [Jia et al. (2009). Acta Cryst. E65, o2490–o2490].
