Abstract: The title compound, C₂₄H₅₆N₆O₂Te₄²⁺·2I^-·C₂H₃N or H[(^tBuNH)Te(-N^tBu)₂Te(-O)]₂(I)₂·MeCN, provides the first example of the cis form of an imidotelluroxane dication. The basket-shaped structure is bispirocyclic, with a `backbone' TeTeTeTe pseudo-torsion angle of -31.51  (3)°. The structure exhibits two ionic TeI interactions [3.4103  (8) and 3.445  (1)  Å] and two TeI close contacts [3.863  (1) and 3.924  (1)  Å] within the molecule, and two TeI close contacts [3.651  (1) and 3.703  (2)  Å] between ions. The intermolecular close contacts connect the cations into pairs which are linked by a weak TeI contact [4.090  (1)  Å] to form an infinite chain.
