The syntheses of [(CH 3 ) 3 Te]X {X = N 3 ( 1 ), OCN ( 2 ), SCN ( 3 ), SeCN ( 4 ), [Ag(CN) 2 ] ( 5 )} and [(C 6 H 5 ) 3 Te]X {X = N 3 ( 6 ), SeCN ( 7 ), [Ag(CN) 2 ] ( 8 )}, their NMR spectroscopic data, vibrational spectra and single crystal structures are described. Compounds 1 − 4 are the first trimethyltelluronium pseudohalides, while the known compounds 6 and 7 have been prepared for completion of their analytical and structural properties. The occurrence of intermolecular Te ··· N, Te ··· O, Te ··· S and Te ··· Se contacts is thoroughly studied. The dicyanoargentates 5 and 8 were obtained in an attempt to prepare telluronium cyanides. Low‐temperature 13 C NMR spectroscopy of the [Ag(CN) 2 ] − ion in solution has been carried out, with determination of the 13 C− 107/109 Ag coupling.
