Abstract

In the title hydrated coordination polymer, {[Zn(C6H2O5)(C10H8N2)(H2O)]·2H2O}n, an infinite [1-10] chain is formed by the linking of [Zn(C10H8N2)(H2O)]2+ entities by bridging, monodentate furan-2,5-dicarboxylate dianionic linkers. The Zn2+ coordination geometry is a trigonal bipyramid, with one N atom (from 2,2′-bipyridine) and one O atom (from the bridging dianion) in the axial positions. For each ZnII atom, the dihedral angle between the furan ring of its coordinated bridging ligand and its coordinated bipyridine ring system is 87.19 (8)°. O—H...O hydrogen bonds involving both the coordinated and uncoordinated water molecules generate a layer motif parallel to (001).
