Tin-oxychalcogenide supertetrahedral clusters maintained in a MTN zeolite-analog arrangement by coulombic interactions

Abstract

Reported are two tin-oxychalcogenides, composed of discrete T3-like [Sn10O8X16]8− (X = S/Se), which are arrayed in an MTN zeotype by electrostatic interactions with protonated amines.

Zeolite analogues based on oxysulfidometalate supertetrahedral clusters via coulombic interactions

“…SOD, BCT, ABW, RWY, NAB) composed of metal-chalcogenide clusters have been microporous, except ISC-16-MInS (M = Zn/Fe) and T3-SnOX-MTN (X = S/Se) reported recently. [26][27][28][29][30] Hence, construction of metal-chalcogenide clusters through self-assembly processes for the formation of periodic lattices mimicking zeolites and featuring large-pores is a daunting challenge.…”

Lanthanum-Centered Organotin Oxysulfide Clusters with Substitutable Coordinating Amide Solvent Molecules for Tuning Blue Light Emission

“…Organometallic clusters have become a research hotspot because of their unique structural features and potential applications in many fields. − An important branch of them, organotin clusters, especially organotin-oxo or organotin-chalcogenide, has been widely used in optical light-emitting devices, extreme ultraviolet lithography, electrocatalysis, third-order nonlinear response materials, etc. − To date, many types of organotin-O clusters or organotin-S clusters have been reported, e.g., {( n BuSn) 22 Sn 4 O 48 }, {( n BuSn) 34 Na 2 O 54 }, {(PhSn) 4 S 6 }, {[(Me 3 P) 3 AuSn]­[(PhSn) 3 S 6 )]}, and {( n BuSn) 4 M 2 S 8 } (where n BuSn is n -butyltin). − The combination of ≥2 types of VIA-elements into the same organotin coordination system will not only enrich the cluster chemistry but also result in different functions associated with their electronic structures. − Nonetheless, organotin oxychalcogenide hybrid clusters have been less explored, due to the existence of coordination competition from O- and S/Se-atoms, making the realization of single O-based or S/Se-based clusters relatively easy and oxychalcogenide clusters, especially the heterometallic or organometallic oxychalcogenide clusters, extremely challenging.…”
