cis-Di-tert-butyl­amido­tetra-μ-tert-butyl­imido-di-μ-oxo-tetra­tellurium diiodide acetonitrile solvate

The title compound, C₂₄H₅₆N₆O₂Te₄²⁺·2I⁻·C₂H₃N or H[(^tBuNH)Te(μ-N^tBu)₂Te(μ-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' Te...Te...Te...Te pseudo-torsion angle of −31.51 (3)°. The structure exhibits two ionic Te...I inter­actions [3.4103 (8) and 3.445 (1) Å] and two Te...I close contacts [3.863 (1) and 3.924 (1) Å] within the mol­ecule, and two Te...I 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 Te...I contact [4.090 (1) Å] to form an infinite chain.

tert-Butyl­amido­dichloro­phosphine oxide

The monomeric units in the title compound, C₄H₁₀Cl₂NOP, are linked together by N—H...O hydrogen bonds to give parallel linear strands along the b axis.
