摘要

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[ Mn-2(en)(5)](2) center dot 4H(2)O (1, en = ethylenediamine), the neighboring [Mn2Ga4Sn4S20](8-) cores were bridged by two pairs of [Mn-2(en)(5)](4+) complex cations via Mn-S bonds to form one-dimensional (1D) neutral chains. Compound Mn2Ga4Sn4S20[Mn(dien)(2)](4) center dot 2H(2)O (2, dien = diethylenetriamine) contained discrete [Mn2Ga4Sn4S20](8-) cores separated by [Mn(dien)(2)](2+) cations. In compound Mn2Ga4Sn4S20[Mn(teta)](4) (3, 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 1 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 3 were also studied.
