We have developed the extended hypervalent chemistry, which consists of linearσ-type bonds in linearly aligned four or more atoms. Here, we aimed for the establishment of the novel extended hypervalent chemistry containing acetylene unit incorporated in the group 16 elements. Such novel extended hypervalent compounds were prepared that consist of linear molecular(or bond) axes surrounded by atoms helically distributed around the axes. Their structures and properties were determined. Such compounds were also prepared that consist of zig-zag type bonding schemes, which are important to clarify the nature of the novel extended hypervalent bonds. Cyclic system is also under preparation. Inclusion of smaller molecules in the compounds is planning.

我们开发了由线性排列的四个或更多原子中的线性σ型键组成的扩展超价化学，我们的目标是建立包含掺入第16族元素的乙炔单元的新型扩展超价化学。制备了由线性分子（或键）轴组成的化合物，其结构和性质也由锯齿形键合方案组成，这很重要。为了阐明新型扩展超价键的性质，正在计划在化合物中包含更小的分子。
