- A (125)Te Moessbauer study of hexahalotellurates, pentahalotellurates, and tetrahaloaryltellurates
-
The (125)Te Moessbauer spectra of a number of hexahalotellurates have been measured and no significant effects of the size or symmetry of the cation on the Moessbauer parameters were observed.The mixed hexahalotellurates, M2TeX4Y2 (X,Y = Cl, Br, or I), do not exhibit a quadrupole splitting, Δ, and the trends in δ with variation in X and Y are discussed.The pentahalotellurates MTeCl5, MTeBr5, and MTeBr4Cl also yield single line spectra and this is interpreted as evidence of intermolecular bridging.The tetrahaloaryl tellurates MArTeX4 and MArTeX3Y (X,Y = Cl, Br, or I) have been studied and the trends in Δ with variation X and Y are consistent with an additive model.The trends in δ are more complex.
