Abstract:	Compounds (4-FC₆H₄)₃SnSEPh₃ (E=C, Si, Ge, Sn, or Pb) were synthesized or generated in solution. The data on the comparative electronegativity of the Ph₃E groups were obtained from the results of¹⁹F NMR spectroscopy. It was established that, except for E=C, the electronegativity changes in parallel with the absolute electronegativity of the central atom. Possible reasons for the deviation observed are discussed.
