Two germanium thioantimonates Co(dien)(2)GeSb(4)S(10) (1, dien = diethylenetriamine) and [Mn(en)(3)]GeSb(2)S(6) (2, en = ethylenediamine) have been solvothermally synthesized and characterized by IR, UV/Vis, fluorescence spectroscopy, elemental analysis, thermogravimetric analysis, powder X-ray diffraction and single-crystal X-ray diffraction. 1 contains heterometallic pseudosemicube [GeSb(2)S(7)] clusters and chain-like Sb(4)S(10) tetramers, which are interconnected to form a unique double layer of GeSb(4)S(10) with 10-MR helical channels. 2 features a sheet layer of GeSb(2)S(6) with ellipse-like 12-MR, where one [GeS(4)] tetrahedra, one [SbS(3)] trigonal-pyramid and one Ψ-[SbS(4)] trigonal bipyramid are combined to form another heterometallic [GeSb(2)S(8)] cluster as a building unit. 1 and 2 exhibit absorption edges at 2.36 eV and 2.10 eV, respectively. 2 exhibits a fluorescence emission at room temperature.
两种锗硫锑酸盐[Co(dien)(2)]2GeSb4S10（1，dien=二乙三胺）和[Mn(en)3]GeSb2S6（2，en=乙二胺）已通过溶剂热法合成，并通过 IR、UV/Vis、荧光光谱、元素分析、热重分析、粉末 X 射线衍射和单晶 X 射线衍射进行了表征。1 包含杂核假四面体形[GeSb2S7]簇和链状 Sb4S10 四聚体，它们相互连接形成独特的双层[GeSb4S10]4-，其中有 10-MR 螺旋通道。2 具有[GeSb2S6]2-片状层，其中有椭圆形 12-MR，其中一个[GeS4]四面体、一个[SbS3]三角锥和一个Ψ-[SbS4]三角双锥组合形成另一个杂核[GeSb2S8]簇作为构建单元。1 和 2 的吸收边缘分别在 2.36 eV 和 2.10 eV。2 在室温下表现出荧光发射。
