4,4′-Bipyridine–cyclohexane-1,2,4,5-tetracarboxylic acid (1/1)

Abstract

In the title 1:1 adduct, C10H8N2·C10H12O8, the dihedral angle between the pyridine rings in the 4,4-bipyridine molecule is 8.33 (13)°. In the crystal, the cyclohexane-1,2,4,5-tetracarboxylic acid molecules interact with each other through intermolecular O—H...O hydrogen bonds, forming an infinite chain along the a axis, which is further linked perpendicularly by O—H...N hydrogen bonds involving bipyridine, resulting in a supramolecular corrugated sheet parallel to the (110) plane.
