13C and 119Sn NMR spectra of the title compounds (C6H5)3SnOC(O)C6H4-4-X, where X = H, NH2, OCH3, C(CH3)3, CH3, NHCOCH3, Cl, and NO2, have been studied in coordinating (pentadeuteriopyridine, hexadeuteriodimethyl sulphoxide) and non-coordinating solvents (deuteriochloroform). From the NMR spectral parameters it follows that all the compounds studied, dissolved in the coordinating solvents, form donor-acceptor complexes with one solvent molecule. Discussed are the differences in composition and structure of the compounds in the two types of solvents as well as influence of substituents on values of the parameters of the 13C and 119Sn NMR spectra.
