Attempts to prepare selenium-rich species resulted in the formation of elemental selenium or Se(3)N(2)Cl(2). The experimental work was supported by ab initio MO calculations which establish the structural and stability relationships of the different members of the series 1,3-Se(x)()S(4)(-)(x)()N(2) (x = 0-4). Full geometry optimization was carried out for each molecular species using the polarized split-valence
[(Me(3)Si)(2)N](2)S与等摩尔量的SCl(2)和S(2)Cl(2)的反应产生S(4)N(2)的收率很高。[(Me(3)Si)(2)N](2)S与S(2)Cl(2),Se(2)Cl(2)和SeCl(3:1:1)的反应4)产生深棕红色不溶物,根据元素分析,质谱,振动分析和NMR光谱推断其主要为SSeSNSN。尝试准备富含硒的物种导致元素硒或Se(3)N(2)Cl(2)的形成。实验工作得到了从头算MO的支持,该计算确定了1,3-Se(x)()S(4)(-)(x)()N(2)系列不同成员的结构和稳定性关系。 (x = 0-4)。使用极化分裂价MIDI-4基集对每个分子种类进行了完整的几何优化。考虑了涉及二阶Møler-Plessett微扰理论的电子相关性的影响。发现每个分子都位于为1,3-S(4)N(2)建立的近似半椅构型(即相互作用的平面NEN和EEE片段; E = S,Se
