Benzene-1,3-dicarboxylic acid-1,2-bis(4-pyridyl)ethene (1/1)

In the title compound, C(12)H(10)N(2)center dot C(8)H(6)O(4), the asymmetric unit contains two halves of 1,2-bis(4-pyridyl)ethene (bpe) molecules and one benzene-1,3-dicarboxylic acid (1,3-H(2)BDC) molecule. These bpe and 1,3-H(2)BDC molecules are linked by classical O-H center dot center dot center dot N hydrogen bonds, forming an extended one-dimensional zigzag chain. Each chain is further linked with neighboring ones by pi-pi interactions between the pyridine and aromatic rings [centroid-centroid distances = 3.9306 (15) angstrom] and the pyridine rings of pairs of symmetry-related molecules [centroid-centroid distances = 3.5751 (15), 3.7350 (15) and 3.6882 (15) angstrom], with the formation of a three-dimensional supramolecular framework.
