Abstract
The crystal structure of the title compound, {[Co(C10H8N2)(H2O)4](C7H3NO4)·3H2O}n, consists of CoII polymeric complex cations, uncoordinated pyridine-3,5-dicarboxylate anions and lattice water molecules. The CoII cation is coordinated by two N atoms from two 4,4′-bipyridine ligands and four water molecules in a distorted octahedral geometry. The 4,4′-bipyridine ligands bridge Co cations, forming a polymeric chain running along the b axis. The two pyridine rings of the 4,4′-biyridine are twisted to each other by a dihedral angle of 8.95 (9)°. Extensive O—H⋯O hydrogen bonding network is present in the crystal structure.
