A new layered indium selenide, [C(7)H(10)N][In(3)Se(5)] (1), has been prepared solvothermally using 3,5-dimethylpyridine as a solvent and structure-directing agent. This material, which was characterized by single-crystal and powder X-ray diffraction, thermogravimetric analysis, UV-vis diffuse-reflectance spectroscopy, IR spectroscopy, and elemental analysis, crystallizes in the monoclinic space group P2(1)/c [a = 3.9990(4) Å, b = 16.7858(15) Å, c = 23.930(2) Å, and β = 94.728(4)°]. The crystal structure of 1 contains anionic layers of stoichiometry In(3)Se(5) in which indium atoms with octahedral and tetrahedral coordination coexist. The In(3)Se(5) layers are interspaced by monoprotonated 3,5-dimethylpyridinium cations. A closely related material, [C(7)H(10)N][In(3)Se(5)] (2), was obtained when using 2,6-dimethylpyridine instead of 3,5-dimethylpyridine.
一种新型的层状硒化铟，[C(7)H(10)N][In(3)Se(5)]（1），已经通过溶剂热法使用 3,5-二甲基吡啶作为溶剂和结构导向剂制备得到。这种材料通过单晶和粉末 X 射线衍射、热重分析、UV-vis 漫反射光谱、IR 光谱和元素分析进行了表征，它结晶在单斜空间群 P2(1)/c [a = 3.9990(4) Å, b = 16.7858(15) Å, c = 23.930(2) Å, and β = 94.728(4)°]。1 的晶体结构包含具有八面体和四面体配位的铟原子共存的化学计量比的阴离子层In(3)Se(5)。In(3)Se(5)层由单质子化的 3,5-二甲基吡啶阳离子隔开。当使用 2,6-二甲基吡啶代替 3,5-二甲基吡啶时，可以得到与之密切相关的材料[C(7)H(10)N][In(3)Se(5)]（2）。
