Abstract: All three title compounds, prepared from bis(3,5-dimethyl-2-nitrophenyl)ditellurium, exhibit high degrees of intramolecular Te-O coordination. Their Te-O distances increase in the order C₈H₈BrNOTe < C₈H₈BrNO₂Te < C₈H₈Br₃NO₂Te, with distances of 2.165  (3), 2.306  (1) and 2.423  (6)  Å, respectively, indicating that C₈H₈BrNOTe may be more aptly described as 1-bromo-4,6-dimethyl-2,1,3-benzoxatellurazole.

Formula: C₈H₈Br₃NO₂Te, C₈H₈BrNO₂Te and C₈H₈BrNOTe
