Abstract: | The title compound, [CoII(C10H8O6)(C10H8N2)(H2O)2]n, was obtained by the hydrothermal reaction of CoSO4 with benzene‐1,4‐dioxydiacetate [systematic name: p‐phenylenebis(oxyacetate)] and 4,4′‐bipyridine (4,4′‐bpy). The Co atom lies at an inversion center and the benzene‐1,4‐dioxydiacetate and 4,4′‐bipyridine moieties lie about other inversion centers. The benzene‐1,4‐dioxydiacetate ligands bridge the octahedral CoII coordination centers, forming a one‐dimensional zigzag chain. The chains are further bridged by 4,4′‐bpy ligands, forming a novel two‐dimensional supramolecular architecture. Hydrogen‐bonding interactions between the coordinated water molecules and the carboxylate O atoms lead to the formation of a three‐dimensional network structure. |
