title: [Mn2Ga4Sn4S20](8-) T3 supertetrahedral nanocluster directed by a series of transition metal complexes.
abstract: With different transition metal (TM) complexes as structure directing agents or building units, three new multinary chalcognidometalates based on T3 supertetrahedral nanocluster of [Mn2Ga4Sn4S20](8-) have been solvothermally synthesized and structurally characterized. In compound Mn2Ga4Sn4S20[Mn2(en)5]2·4H2O (, en = ethylenediamine), the neighboring [Mn2Ga4Sn4S20](8-) cores were bridged by two pairs of [Mn2(en)5](4+) complex cations via Mn-S bonds to form one-dimensional (1D) neutral chains. Compound Mn2Ga4Sn4S20[Mn(dien)2]4·2H2O (, dien = diethylenetriamine) contained discrete [Mn2Ga4Sn4S20](8-) cores separated by [Mn(dien)2](2+) cations. In compound Mn2Ga4Sn4S20[Mn(teta)]4 (, teta = triethylenetetramine), each [Mn2Ga4Sn4S20](8-) core was covalently attached by four [Mn(teta)](2+) complexes via terminal Mn-S bonds to form a neutral isolated cluster. The photocatalytic experiments indicate that compound was able to degrade rhodamine B (RhB) and crystal violet (CV) under visible irradiation. Furthermore, the luminescence properties and thermal stabilities of the title compounds, as well as the second-order nonlinear optical property of were also studied.
