catena-Poly[[diaqua­bis­[2-(3-oxo-1,3-di­hydro-2-benzofuran-1-yl)acetato-κO]cobalt(II)]-μ-1,2-bis­(pyridin-4-yl)ethane-κ²N:N′]

In the title complex, [Co(C₁₀H₇O₄)₂(C₁₂H₁₂N₂)(H₂O)₂]_n, the Co^II 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 Co^II ions into infinite chains extending parallel to [010]. In these chains, there are intra-mol­ecular O—H...O hydrogen bonding between the coordination water mol­ecules and carboxyl­ate groups. Inter-mol­ecular O—H...O hydrogen bonding between the adjacent chains and π...π stacking inter­actions result in the formation of a three-dimensional supra­molecular network.
