The title compound, {(C6H21N4)[V3O9]·H2O}n, crystallizes as a salt with [trenH3]3+cations [tren is tris(2-aminoethyl)amine], and one-dimensional anionic {[VVO3]−}n(metavanadate) chains along thec-axis direction. Three crystallographically distinct VVsites and one occluded water molecule are present for every [trenH3]3+cation in the unit cell. The {[VVO3]−}nchains are composed of vertex-sharing [VO4] tetrahedra and have a repeat unit of six tetrahedra. Each tetrahedron in the chain contains two terminal and two μ2-bridging oxide ligands. The [trenH3]3+cations, {[VVO3]−}nanions and occluded water molecules participate in an extensive three-dimensonal hydrogen-bonding network. The three terminal ammonium sites of the [trenH3]3+cations each form strong N—H...O hydrogen bonds to terminal oxide ligands on the {[VVO3]−}nchain. Each occluded water molecule also donates two O—H...O hydrogen bonds to the terminal oxide ligands.

The asymmetric unit of the title compound, C10H9N2 +·0.5C2O4 2−·C2H2O4·H2O, consists of a 2,2′-bipyridinium cation, half an oxalate dianion, one oxalic acid and one water molecule. One N atom in 2,2′-bipyridine is unprotonated, while the second is protonated and forms an N—H...O hydrogen bond. In the crystal, the anions are connected with surrounding acid molecules and water molecules by strong near-linear O—H...O hydrogen bonds. The water molecules are located between the anions and oxalic acids; their O atoms participate as donors and acceptors, respectively, in O—H...O hydrogen bonds, which form sheets arranged parallel to the ac plane.

In the mononuclear title compound, [Cd(C8H5O3)2(C10H8N2)(H2O)]·H2O, the Cd atom is O,O′-chelated by two 4-formylbenzoate monoanions and N,N′-chelated by 2,2′-bipyridine. It is also coordinated by a water molecule in a monocapped trigonal-prismatic geometry. The coordinated and solvent water molecules and O atoms of the monoanions engage in hydrogen bonding, resulting in a chain running along the b axis of the monoclinic unit cell.

The chloride anions are also linked by two weak C—H...Cl interactions to neighbouring methylene groups and imidazole rings. Two imidazolium moieties form a homoconjugated cation through a strong and asymmetric O—H...O hydrogen bond of 2.472 (2) Å. The IR spectrum shows a continuous D-type absorption in the region below 1300 cm−1and is different to that of 1-carboxymethyl-3-methylimidazolium chloride [Xuan, Wang & Xue (2012).Spectrochim. Acta Part A,96, 436–443].
