The title compound, {[Cd(C6H16N2)(H2O)4](C8H4O4)·2H2O}n, (I), exhibits a chain structure. The central CdII ion is coordinated by four water molecules and two N atoms derived from two 1,6-diaminohexane molecules, giving a zigzag-shaped polymeric chain with a [Cd—N—C—C—C—C—C—C—N]n backbone running parallel to the b axis. The two independent terephthalate anions are not coordinated to cadmium(II), acting rather as counter-ions. Each coordinated water molecule forms strong O—H
O hydrogen bonds with the adjacent terephthalate counter-ions, forming a three-dimensional hydrogen-bonded supramolecular architecture.

The title compound, [Cu(C3H10N2)2(H2O)2](C8H4O4)·2H2O, is a mononuclear complex. The CuII atom is coordinated by four N atoms from two 1,2-propanediamine ligands and two O atoms from two water molecules, to form a distorted octahedral geometry. All the N atoms of the 1,2-propanediamine ligands, and all the O atoms in the water molecules and terephthalate anions, contribute to the formation of a hydrogen-bonded three-dimensional network.

The title compound, [Zn(C8H7O3)2(H2O)2], is a mononuclear complex. The ZnII atom lies on a twofold axis and is coordinated by four O atoms from two 4-formyl-2-methoxyphenolate anionic ligands and two O atoms from two water molecules, to form a very distorted tetragonal-bipyramidal geometry. The formyl O atoms of the ligand, the water O atoms and the phenolate O atoms contribute to the formation of a hydrogen-bonded three-dimensional network.

The title compound, C14H13NO2, contains two aromatic rings, which are bridged by a C=N unit. The 4-hydroxy-3-methoxyphenyl and phenyl groups are trans to each other. The molecular structure is stabilized by an intramolecular O—HO hydrogen bond. In addition, there is an intermolecular O—HN hydrogen bond and intermolecular C—HO close contacts. There are two molecules in the asymmetric unit.
