چکیده
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.
