The N-methyl benzotellurodiazolylium cation self-associates in the solid state via short (2.471(3) Å) 4-center Te⋯N′ intermolecular contacts; electrochemical data and the results of DFT calculations suggest that the dimers persist in solution.

Comprehensive structural, spectroscopic, and quantum chemical analyses of new donor–acceptor complexes between N‐heterocyclic carbenes and 1,2,5‐telluradiazoles and a comparison with previously known complexes involving tellurenyl cations showed that the dative C−Te bonds cannot be solitarily described with only one Lewis formula. Canonical Lewis formulas that denote covalency and arrows emphasizing

Being isoelectronic and isostructural analogues of N-alkyl-substituted telluradiazolyl cations, the adducts of triphenylborane with benzo-2,1,3-telluradiazole provide an electrically neutral point of reference with which the properties of the heterocyclic ions can be compared.
