摘　　要：标题化合物采用锌粉、硫粉及２－甲基吡啶直接反应最后得到金黄色晶体，其具有萤光性能，它不溶于水及二硫化碳．进行Ｘ－射线结晶学表征，该分子中含有四面体配位的ＺｎＳ２Ｎ２核心．结晶学参数：单斜晶系，ＣＣ，Ｚ＝４，ａ＝０．７５１３６（２４）ｎｍ，ｂ＝１．７３０６５（７９）ｎｍ，ｃ＝１．３６８１２（３７）ｎｍ，α＝９０．０１８°（３０），β＝９４．４４９°（２７），γ＝８９．９４７°（４２），Ｖ＝１．７７３６６ｎｍ３．通过元素分析其化学式为ＺｎＳ６（Ｃ６Ｈ７Ｎ）２．对标题化合物进行红外光谱归属，同时进行热分析，循环伏安以及荧光性能的研究，发现温度大于１０４℃时开始分解，于３８０℃全部分解。The title compound has been obtained by reaction of zinc powder with sulfur in 2-methylpyridine. The colour of the crystal is gold-yellow, the compound is insoluble in water and carbon dissulfide. The crystal data for the title compound are : monoclinicC c,Z=4,a=0.75136(24)nm,b=1.73065(79)nm,c=1.36812(37)nm,α=90.018°(30),β=94.449°(27),γ=89.947°(42),V=1.77366nm 3.It′s chemical formula ZnS 6(C 6H 7N) 2has been determined by elemental analysis. The IR spectra of the title compound are assigned. At the same time, thermal analysis, cyclic voltammetry and fluorescence of the title compound have been studied. It shows that the title compound has fluorescence, and starts to decompose at over 104℃ and decomposes completely at above 380℃. The final product is ZnS.
