چکیده
The title cocrystal, C(10)H(8)N(2)·C(6)H(6)O(4), crystallizes with half-mol-ecules of 4,4'-bipyridine and trans,trans-hexa-2,4-dienedioic acid in the asymmetric unit, as each is located about a crystallographic inversion center. The bipyridine molecule is planar from symmetry. In the dicarboxylic acid molecule, the O-C-C-C torsion angle is -13.0 (2)°. In the crystal, O-H⋯N and C-H⋯O hydrogen bonds generate a three-dimensional network.

The title 1:1 co-crystal, C(6)H(12)N(2)·C(6)H(6)O(4), the dicarb-oxy-lic acid mol-ecule is close to planar [r.m.s. deviation from the mean plane = 0.07 (1) Å]. In the crystal, the two mol-ecules are arranged alternately and are linked by O-H⋯N hydrogen bonds, leading to the formation of a chain along the [20-1] direction. The chains are assembled into a two-dimensional framework parallel to the...
