Highlights: [•] H3PW12O40/Ag–TiO2 catalyst exhibited excellent degradation efficiency towards AT. [•] The influencing factors on degradation kinetics of aqueous AT were studied in detail. [•] The hydroxyl radicals was the major reactive oxygen species during the AT degradation. [•] The possible AT photodegradation pathways using H3PW12O40/Ag–TiO2 were proposed. [ABSTRACT FROM AUTHOR]

Abstract: An organic–inorganic hybrid compound, (Bu4N)2[Mo6O18(NAr)] (Ar= p-BrC6H4) has been synthesized via the DCC dehydrating protocol of the reaction of [α-Mo8O26]4− with 4-bromoaniline hydrochloride in anhydrous acetonitrile, which has been characterized by UV–Vis spectra, 1H NMR and single crystal X-ray diffraction study. By comparing the UV–Vis spectra, which were used to monitor the reaction, the optimum preparative condition for this compound was also determined. This compound crystallizes in the monoclinic space group P21/n, which is featured in a terminal para-bromophenylimido group linked to an Mo atom of a hexamolybdate cluster by a Mo–N triply bond. In addition, there are π–π dimerization of the neighboring cluster anions though the parallel aromatic rings in their crystals. [Copyright &y& Elsevier]
