The 125Te Moessbauer and nmr spectra of the compounds (R3X)2Te (R = Me, X = C, Si, Ge, and Sn; R = Ph, X = Ge and Sn), R3MTePh (R = Me, X = Si, Ge, and Sn; R = Ph, X = Ge, Sn, Pb), R2Sn(TePh)2 (R = Me and t-Bu), and the cyclic compounds (Me2SnTe)3, (Me2Sn)3Te2, and (t-Bu2SnTe)2 have been measured.The trends in the Moessbauer and nmr data are discussed.The Moessbauer quadrupole splittings increase as the nmr chemical shifts become more positive, corresponding to a decrease in the shielding at the tellurium nucleus.The 119Sn Moessbauer and nmr parameters of the compounds (R3Sn)2E and R3SnEPh (R = Me and Ph), (Me2SnE)3, (Me2Sn)2E2, (t-Bu2SnE)2, and Me2Sn(EPh)2 (E = S, Se, and Te) are discussed.The 119Sn Moessbauer quadrupole splittings are again observed to increase as the nmr chemical shifts become more positive.The 125Te and 119Sn nmr and Moessbauer data provide evidence that there is little transmission of bonding effects through the tin-tellurium bond as the chemical environment about the tin or tellurium is changed.
