Abstract

Formally uncharged two-coordinate tellurium atoms in trialkyl(telluroseleno)phosphonium salts [(tBu₂iPrPSeTe-p-Tol)⁺ (p-TolTeI₂)⁻] (2a) and {[(iPr₃PSeTeI)⁺]₂ (TeI₆)²⁻} (5) behave as soft acceptors towards iodotellurate anions, thus exhibiting a novel type of Te⋯Te anion → cation donor–acceptor interaction (2a) and a chelating Te^IV(µ-I)₂Te^II anion–cation coordination (5) in the solid state.
