In the title complex, [Co(C10H7O4)2(C12H12N2)(H2O)2]n, the CoII ion is located on a crystallographic centre of symmetry and is six-coordinated by two N atoms from two 1,2-bis(4-pyridyl)ethane ligands, two carboxylate O atoms from two 1,3-dihydro-3-oxo-1-isobenzofuranacetate ligands and two terminal water ligands. The 1,2-bis(4-pyridyl)ethane ligands act as bidentate ligands, and bridge the CoII ions into infinite chains extending parallel to . In these chains, there are intra-molecular O-HO hydrogen bonding between the coordination water molecules and carboxylate groups. Inter-molecular O-HO hydrogen bonding between the adjacent chains and stacking interactions result in the formation of a three-dimensional supramolecular network.
