摘要

Presented are the ionothermal syntheses, characterizations, and photodegradation properties of four isostructural chalcogenidometalate compounds, namely, [Bmmim]_(5)[In_(10)Q_(16)Cl_(3)(Bim)] (Q = S ( IL-InS-1 ), S_(7.12)Se_(8.88) ( IL-InSSe-2 ), Se ( IL-InSe-3 ), Se_(13.80)Te_(2.20) ( IL-InSeTe-4 ); Bmmim = 1-butyl-2,3-dimethylimidazolium, Bim = 1-butyl-2-methylimidazole). According to the single-crystal X-ray diffraction analysis, the title compounds belong to the C 2/ c space group and feature isolated supertetrahedral T3 anionic units of [In_(10)Q_(16)Cl_(3)(Bim)]~(5–) stabilized by [Bmmim]~(+) cations. The ionic liquid not only provided the [Bmmim]~(+) as the counterions but also acted as the reactive solvent releasing [Bim] ligands that are covalently bonded to In atoms. Unlike the widely reported extended frameworks that contain T3 InS/Se as building units, IL-InSe-3 represents the first example of discrete T3 InSe clusters, and the InTe-based discrete T3 cluster ( IL-InSeTe-4 ) was characterized for the first time. The optical absorption edges of the title compounds showed gradual red shifts along with the change of chalcogens from S, S/Se, Se, to Se/Te. As a result, their photocatalytic activities were tunable with the optical response moving from the ultraviolet (UV) to visible light region.
