“…Exceptions are the radical anions of octaisopropylcyclotetrasilane and octa-sec-butylcyclotetrasilane where ESR spectra indicated bent structures. 40 Some selected dihedral angles of further cyclotetrasilanes are given in Table cally compared to larger ring systems. They usually appear around 300 nm.…”

The radical anion of octa-tert-butyloctasilacubane was generated and isolated. The EPR spectrum showed the satellites due to the tertiary 13 Cn uclei of the eight tert-butyl groups.T he X-rayc rystallographic analysis showed that the SiÀSi bonds are shortened and the SiÀCb onds are elongated compared with those of octa-tert-butyloctasilacubane.T hese results are well explained by the distribution of an unpaired electron in the singly occupied molecular orbital (SOMO).

The radical anion of octa-tert-butyloctasilacubane was generated and isolated. The EPR spectrum showed the satellites due to the tertiary (13)C nuclei of the eight tert-butyl groups. The X-ray crystallographic analysis showed that the Si-Si bonds are shortened and the Si-C bonds are elongated compared with those of octa-tert-butyloctasilacubane. These results are well explained by the distribution of an unpaired electron in the singly occupied molecular orbital (SOMO).

A BENT CYCLOPOLYSILANE ANION-RADICAL (i-Pr2Si)4

Abstract: The ESR spectra for (i-Pr2Si)4\ewdot and (s-Bu2Si)4\ewdot show two equally-intense splitting constants for α-13C, indicating that these anion-radicals are bent and not rapidly interconverting.
