Abstract

A novel inorganic-organic hybrid selenidoantimonate material, [M 1 (C 4 H 13 N 3 ) 2 ] n [M 2 Sb 2 Se 5 ] n (M 1 = Mn、Co, M 2 = Zn、Cd), was synthesized by solvothermal reaction. Dien(diethylenetriamine) was used as a template-directed reagent. Until now, this compound, to the best of our knowledge, is the first selenidoantimonate, in which zinc and cadmium incorporated into the SbSe 3 framework, leading to the formation of ZnSbSe 5 and CdSbSe 5 . Furthermore, because of the ZnSe 4 and CdSe 4 units in the framework, all the compounds exhibit emission of fluorescence. By the same way, it is possible to synthesize series of compounds with similar novel structure and potential application value in luminescence area.
