Photocatalytic properties of two POM-templated organic–inorganic hybrid compounds

• Two POM-templated organic–inorganic hybrid compounds were synthesized.
• Compounds 1–2 were both 3D supramolecules packing through weak interactions.
• Photocatalytic activity of compounds 1–2 was investigated under UV light.

Reported are the rational synthesis, structures and properties of two novel organic–inorganic hybrid compounds, [Ag3(3-bpo)4(PMo12O40)]·~ 1.5H2O (1) and [Ag4(3-bpo)2(CH3CN)2(SiW12O40)] (2), where 3-bpo = 2,5-bis(3-pyridyl)-1,3,4-oxadiazole. Crystal structural analysis indicates that compound 1 exhibits one dimensional zigzag chains with the discrete [PMo12O40]3 − anions as guest molecules. While in compound 2 the POM anions as μ2-linkage bridging two chains construct supramolecular sheet. Both compounds were synthesized under hydrothermal conditions and characterized by single-crystal X-ray diffraction, IR spectroscopy, elemental analysis and TG. Furthermore, the excellent photocatalytic activity of compounds 1–2 was investigated under UV light irradiation.
