Abstract
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.
摘要
标题共晶体C(10)H(8)N(2)·C(6)H(6)O(4)在不对称单元中与4,4'-联吡啶和反,反-己-2,4-二烯二酸的半分子结晶，因为每个分子都位于一个晶体学倒转中心周围。联吡啶分子由于对称性而呈平面状。在二羧酸分子中，O-C-C-C扭转角为-13.0 (2)°。在晶体中，O-H⋯N和C-H⋯O氢键形成了一个三维网络。
