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 →
