Telluroselenophosphonium ions: their unusual soft–soft interactions with iodotellurate anions

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 TeIV(µ-I)2TeII anion–cation coordination (5) in the solid state.
