Here three new types of cluster-based tin oxysulfides are reported. Single-crystal X-ray diffraction analysis reveals that both compound 1 [Sn](2)[Sn40O16S74](DMA)(4)(DEA)(10)(H+-DEA)(12)(H2O)(20) (DMA = dimethylamine, DEA = diethylamine) and compound 3 [Sn][Sn40O16S74](H+-DMA)(12)(DEA)(4)(H-2(2+)-DACH)(3)(H2O)(20)(DACH = 1,2-diaminocyclohexane) are built from oxygen-stuffed supertetrahedral T3-SnOS clusters with corner-sharing S2- and single Sn2+ ion as bridging linkers, and compound 2 [Sn40O16S73]- (DMA)(H+- TMA)(18)(H2O)(14) (TMA trimethylamine) is constructed by the interrupted supersupertetrahedral T3,2 clusters. Such variable and unique linkage modes are very useful for constructing other types of cluster-based crystalline open-framework chalcogenides. In addition, compound 2 is the first case that displays photoluminescence emission among T3-SnOS-based chalcogenides.
