摘要：

[4,6-Di-tert-butyl-N-(2,6-diisopropylphenyl)-o-iminobenzosemiquinonato]thallium(I) was synthesized and characterized by IR and ESR spectroscopy. The hyperfine coupling constants with Tl-203/205 nuclei were found to depend strongly on the nature (solvating ability) of solvents. At 298 K, the HFC constant a(Tl) changes from 3.09 mT in n-hexane up to 19.70 mT in tetramethylethylenediamine. The coordination number of solvation was found to be 1 for DMF-benzene and pyridine-hexane systems. The thermodynamic characteristics of solvation in the pyridine-hexane system were determined.
