1,2-Bis(pyridin-4-yl)ethene–4-hydroxy-3-methoxybenzoic acid (1/1)

Abstract

In the title 1:1 co-crystal [alternatively called bipyridine ethylene–p-vanillic acid (1/1)], C12H10N2·C8H8O4, the dihedral angle between the pyridine rings is 59.51 (5)°. In the crystal, the molecules are linked by O—H...N hydrogen bonds, generating [401] chains of alternating C12H10N2 and C8H8O4 molecules.
