Self-association of the N-methyl benzotellurodiazolylium cation: implications for the generation of super-heavy atom radicals.

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