In the title 1:1 adduct, C(10)H(8)N(2)·C(10)H(12)O(8), the dihedral angle between the pyridine rings in the 4,4-bipyridine molecule is 8.33 (13)°. In the crystal, the cyclo-hexane-1,2,4,5-tetra-carb-oxy-lic acid mol-ecules inter-act with each other through inter-molecular 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 supra-molecular corrugated sheet parallel to the (110) plane ...[more]
