title: catena-Poly[bis[tetraaquacobalt(II)-mu-4,4'-bipyridine-kappa 2N:N'] benzene-1,2,4,5-tetracarboxylate(4-) dihydrate].
abstract: The title compound, [Co(C(10)H(8)N(2))(H(2)O)(4)](2)(C(10)H(2)O(8)) x 2H(2)O, consists of two crystallographically independent Co(II) atoms linked by 4,4'-bipyridine ligands into one-dimensional chains, which are further connected into a three-dimensional framework linked by [C(6)H(2)(COO)(4)](4-) anions and water molecules, achieved through complex hydrogen bonding.
