[Mn2Ga4Sn4S20](8-) T3 supertetrahedral nanocluster directed by a series of transition metal complexes.

With different transition metal (TM) complexes as structure directing agents or building units, three new multinary chalcognidometalates based on T3 supertetrahedral nanocluster of Mn2Ga4Sn4S20 have been solvothermally synthesized and structurally characterized. In compound Mn2Ga4Sn4S20[Mn2(en)5]2·4H2O (, en = ethylenediamine), the neighboring Mn2Ga4Sn4S20 cores were bridged by two pairs of Mn2(en)5 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 cores separated by Mn(dien)2 cations. In compound Mn2Ga4Sn4S20[Mn(teta)]4 (, teta = triethylenetetramine), each Mn2Ga4Sn4S20 core was covalently attached by four Mn(teta) 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.
