Tribromo(3,5-dimethyl-2-nitrophenyl-κ2C1,O)tellurium(IV), bromo(3,5-dimethyl-2-nitrophenyl-κ2C1,O)tellurium(II) and bromo(3,5-dimethyl-2-nitrosophenyl-κ2C1,O)tellurium(II)
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.
