| Research Abstract |
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.
