| Abstract: | A study has been made of the EPR spectra of Tl(l) and Tl(III) o-semiquinolates, obtained by the interaction of o-benzoquinones with thallium amalgam and thallium(III) diethyldithiocarbamate, respectively. A strong temperature dependence has been found for the constant of hyperfine coupling (HFC) with the metal nucleus in thallium(III) 3,5-di-tert-butyl-o-semiquinolate; this is explained by the presence of competing mechanisms of spin transfer from the o-semiquinone ligand to the metal. Cation exchange and effective complexation of the Tl(I) o-semiquinolate with thallium diethyldithiocarbamate have been observed. The kinetic parameters of exchange have been determined.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 4, pp. 786–790, April, 1990. |
