In the title 1:1 co-crystal, C12H10N2·C8H7NO4, the bi-pyridine moiety shows whole-mol-ecule disorder over two sets of sites in a 0.588 (3): 0.412 (3) ratio. In the crystal, the components form hydrogen-bonded sheets linked by N-H⋯O and O-H⋯N inter-actions, which stack along the a axis. A comparison to a related and previously published co-crystal of 5-amino-isophthalic acid and the shorter 4,4'-bipryidine is presented.
在标题为1:1的共晶体C12H10N2·C8H7NO4中，联吡啶部分在两组位置上呈现出全分子无序，比例为0.588 (3): 0.412 (3)。在晶体中，各组分通过N-H⋯O和O-H⋯N相互作用形成氢键连接的片层，这些片层沿a轴堆叠。本文还与之前发表的5-氨基间苯二甲酸和较短的4,4'-联吡啶的相关共晶体进行了比较。
