In the title complex, (C18H20N4)[HgI2(C7H3NO4)], the Hg atom exists in a distorted trigonal–bipyramidal geometry formed by two I atoms, one pyridine N and two carboxylate O atoms from a chelating 2,6-pyridinedicarboxylate ligand. Extensive hydrogen bonding between the carboxylate groups and the 1,1′-(butane-1,4-diyl)bis(1H-benzimidazol-3-ium) ion is present in the structure, as well as π–π stacking interactions. The cation has a crystallographic centre of symmetry. In the anion, a crystallographic twofold rotation axis coincides with the Hg–N bond.

The solvothermal reaction of Zn(OAc)2·2H2O with 3,3′-(diazenediyl)dibenzoic acid (H2ADB) in H2O at 393 K afforded the title complex, [Zn(C14H8N2O4)(H2O)]n. The asymmetric unit contains half a ZnIIcation, half an ADB ligand and half a water molecule. Each ZnIIcentre lies on a crystallographic twofold rotation axis and is five-coordinated by four O atoms of bridging carboxylate groups from four ADB ligands and one O atom from a water molecule, forming a distorted trigonal–bipyramidal coordination geometry. The [Zn(H2O)] subunits are bridged by carboxylate groups to give one-dimensional [Zn(μ-COO)4(H2O)]nchains. The chains are linked by ADB ligands into two-dimensional sheets, and these sheets are further connected to neighbouring sheetsviahydrogen bonds (OW—HW...O), forming a three-dimensional hydrogen-bond-stabilized structure with an unprecedented 374175262topology.
