Abstract

In the title complex, {[Pb(C8H7O3)2(H2O)]·H2O}n, the PbII atom is seven-coordinated by six carboxylate O atoms from four different 2-hydroxyphenylacetate (2-dph) ligands and one water molecule, displaying a hemidirected irregular geometry, with the empty side of the metal ion capped by a benzene ring forming a Pb...π contact [Pb...centroid distance = 3.342 (2) Å]. One 2-dph ligand functions in a bridging mode and connects Pb ions into a linear chain. The crystal packing is governed by intra- and intermolecular O—H...O hydrogen bonds.
