In the title compound, [Co2(C12H8O12)(C12H8N2)2]n, each 3,6-dicarboxycyclohexane-1,2,4,5-tetracarboxylate (H2chhc4-) anion has crystallographically imposed C2 symmetry and bridges four six-coordinate Co atoms, generating polymeric chains running along . These chains are further extended into a three-dimensional network via O-HO hydrogen-bonding interactions and interchain - stacking interactions [centroid-centroid distance = 3.662 (2) Å].
