The preparation of several salts of the Me{sub 3}Te{sup +} and Ph{sub 3}Te{sup +} cations is reported along with {sup 125}Te static and CP/MAS solid-state NMR spectra of the Me{sub 3}Te{sup +} salts and {sup 125}Te CP/MAS spectra of the Ph{sub 3}Te{sup +} salts. In addition, crystal structures of the salts Me{sub 3}Te{sup +}Cl{sup {minus}} {times} H{sub 2}O (1), Me{sub 3}Te{sup +}I{sup {minus}} (2), Me{sub 3}Te{sup +}NO{sub 3}{sup {minus}} (3), Ph{sub 3}Te{sup +}NO{sub 3}{sup {minus}} (4), Ph{sub 3}Te{sup +}Cl{sup {minus}} {times}{1/2}CHCl{sub 3} (5), and (Ph{sub 3}Te){sub 2}SO{sub 4} {times} 5H{sub 2}O (6) have been determined to help in the interpretation of some of the above spectra. It is shown that secondary bonding interactions with the anions have significant and substantial influence on the geometries of the cations and their crystal packings and on the resulting NMR spectra in terms of the tellurium shielding tensors and isotropic chemical shifts and in the presence of log-range spin {1/2} to spin 3/2 couplings. These couplings are indicative of long-range covalent interactions between the anions and cations in this series of compounds. In particular, the {sup 125}Te CP/MAS spectrum of Me{sub 3}Te{sup +}Cl{sup {minus}} {times} H{sub 2}O consists of a septet due to coupling to two equivalent chlorine atoms. In the case of 4 and 5 the presence of 4 and 2 crystallographically independent Te atoms is confirmed in the NMR spectra. 38 refs., 11 figs.
