A planar dianionic ditelluride and a cyclic tritelluride supported by P 2 N 2 rings

Oxidation of alkali metal derivatives of [Te((t)BuN)P(μ-N(t)Bu)(2)P(N(t)Bu)Te](2-) with I(2) produces the intermediate ditelluride dianion [Te((t)BuN)P(μ-N(t)Bu)(2)P(N(t)Bu)Te](2)(2-) with a planar PTeTeP conformation and, subsequently, the cyclic tritelluride [((t)BuN)P(μ-N(t)Bu)(2)P(N(t)Bu)(μ-TeTeTe)].
