N-Triphenylboryl- and N,N '-bis(triphenylboryl)benzo-2,1,3-telluradiazole

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.
