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

Abstract

In the title compound, C12H10N2·C8H6O4, the asymmetric unit contains two halves of 1,2-bis­(4-pyrid­yl)ethene (bpe) mol­ecules and one benzene-1,3-dicarb­oxy­lic acid (1,3-H2BDC) mol­ecule. These bpe and 1,3-H2BDC mol­ecules are linked by classical O—H⋯N hydrogen bonds, forming an extended one-dimensional zigzag chain. Each chain is further linked with neighboring ones by π–π inter­actions between the pyridine and aromatic rings [centroid–centroid distances = 3.9306 (15) Å] and the pyridine rings of pairs of symmetry-related mol­ecules [centroid–centroid distances = 3.5751 (15), 3.7350 (15) and 3.6882 (15) Å], with the formation of a three-dimensional supra­molecular framework.
