Molecular and chemical dynamics of a biradical with six-coordinate silicon atom

Russian Chemical Bulletin Aims and scope

Abstract

The intramolecular dynamics of a silicon biradical complex witho-semiquinone ligands was studied in a frozen toluene solution. Analysis of the broadening and shifts of the canonical components in the ESR spectrum of this biradical allows one to detect the abrupt reorientation of the magnetic axes due to intramolecular single bond-unpaired electron exchange. The frequencies of chemical exchange at low temperatures were estimated.
