Tribromo(3,5-dimethyl-2-nitrophenyl-kappa(2)C(1),O)tellurium(IV), bromo(3,5-dimethyl-2-nitrophenyl-kappa(2)C(1),O)tellurium(II) and bromo(3,5-dimethyl-2-nitrosophenyl-kappa(2)C(1),O)tellurium(II).
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 C(8)H(8)BrNOTe < C(8)H(8)BrNO(2)Te < C(8)H(8)Br(3)NO(2)Te, with distances of 2.165 (3), 2.306 (1) and 2.423 (6) A, respectively, indicating that C(8)H(8)BrNOTe may be more aptly described as 1-bromo-4,6-dimethyl-2,1,3-benzoxatellurazole.
