Abstract
In the title compound, [Pb2(C7H4FO2)4(H2O)2]n, one PbII atom is coordinated by seven O atoms and one F atom from five 2-fluorobenzoate ligands, and the other PbII atom is coordinated by five O atoms from four 2-fluorobenzoate ligands and three water molecules, resulting in distorted PbO7F and PbO8 polyhedra. The 2-fluorobenzoate ligands bridge Pb atoms, giving rise to a one-dimensional chain structure extending along the [100] direction. The polymeric chains are connected via C—H⋯O hydrogen bonds and π–π interactions, with an interplanar distance of 3.46 (1) Å. An intramolecular O—H⋯F interaction is also present.

The 2-fluorobenzoate ligands bridge Pb atoms, giving rise to a one-dimensional chain structure extending along the [100] direction. The polymeric chains are connected via C—HÁ Á ÁO hydrogen bonds and – interactions, with an interplanar distance of 3.46 (1) A. An intramolecular O—HÁ Á ÁF interaction is present.
