Five new compounds based on {XM₁₂O₄₀} (X = P, Si, M = W, Mo) were synthesized and characterized by IR, UV–Vis, XRD, cyclic voltammetry and single crystal X-ray diffraction analysis. [Cd₂(phen)₄(inic)(Cl)][HPW₁₂O₄₀] (1, inic = isonicotinic acid, phen = 1,10-phenanthroline), [Cd₂(phen)₄(inic)(Cl)][HPMo₁₂O₄₀]∙H₂O (2), and [Cd₂(phen)₄(nic)(Cl)][HPMo₁₂O₄₀]∙H₂O (3, nic = nicotinic acid) are isostructural and isomorphous to one another. Compounds 1 and 2 are both constructed from [XM₁₂O₄₀]^3- and transition metal mixed-organic-ligand complexes (TMMCs) of inic⁻, whereas compound 3 is formed by [XM₁₂O₄₀]^3- and TMMCs of nic⁻. [Cd₂(phen)₄(pic)][PMo₁₂O₄₀] (4, pic = picolinic acid) is made up of [PMo₁₂O₄₀]^3- and supported cadmium-pic-phen complexes. [Ag(py)₂]_0.75[H_3.25SiW₁₂O₄₀](py) (5, py = pyridine) is based on [H_3.25SiW₁₂O₄₀]^-0.75 and silver complexes of py. It should be noted that py ligands in compound 5 are in-situ synthesized from pic hydrothermally. The photodegradation properties for compounds 1–5 have been studied.
