    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.

    ABSTRACT: In the title complex, [Ag(NO3)(C5H5NO)]n, the AgI atom is coordinated by two O atoms from two different 4-pyridone ligands and two O atoms from one nitrate anion, displaying a nearly planar coordination geometry. The O atoms of two 4-pyridone ligands bridge two symmetrically related AgNO3 units, forming a dimer, with an Ag...Ag separation of 3.680 (2) Å. Neighbouring dimers are linked into an infinite chain through weak Ag...O interactions [2.765 (2) Å], Ag...Ag interactions [3.1511 (4) Å] and π–π stacking interactions [centroid–centroid distance = 3.623 (4) Å]. N—H...O and C—H...O hydrogen bonds assemble these chains into a three-dimensional network.
