| Abstract: | Three new POM-templated organic–inorganic compounds, Cu2(3,5-bptp)2H2SiW12O40]·4H2O (1), Ag2(3,5-bptp)2HPW12O40]·4H2O (2), Cu4(OH)3Cl(H2O)3(4-bpo)3](SiW12O40)·5H2O (3) (3,5-bptp = 3,5-bis(3-(pyrid-4-yl)-1,2,4-triazolyl)-pyridine, 4-bpo = 2,5-bis(4-pyridyl)-1,3,4-oxadiazole) were hydrothermally synthesized and characterized by elemental analysis and single crystal X-ray diffraction. Crystal structural analysis indicates that compounds 1 and 2 are isostructural and show one dimensional zigzag chains with H2SiW12O40]2 − as guest molecules. Compound 3 is two dimensional sheets constructed from Cu4(OH)3Cl(H2O)3] clusters and 4-bpo ligands with SiW12O40]4 − as guest molecules. Furthermore, the photocatalytic degradation of methyl orange (MO) with 3 was studied under visible light irradiation, indicating excellent photocatalytic activity. |
