Abstract

In the crystal structure of the title compound, [Zn(C6H2O5)(H2O)3]n, an infinite chain is formed along [001] by linking of the Zn(H2O)3 entities with one carboxyl­ate group of the furan-2,5-dicarboxyl­ate ligand. Adjacent chains are linked by Owater—H⋯O hydrogen-bonding inter­actions. The Zn(H2O)3O3 polyhedron displays a distorted octa­hedral geometry with one weak Zn—Ocarboxyl­ate coordination [2.433 (8) A°] and two water mol­ecules located in axial positions. Except for one of the axial water molecules and two adjacent H atoms, the other atoms (including H atoms) possess site symmetry m.
