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) Angstrom, respectively, indicating that C8H8BrNOTe may be more aptly described as 1-bromo-4,6-dimethyl-2,1,3-benzoxatellurazole.
