Telluroselenophosphonium ions: their unusual soft-soft interactions with iodotellurate anions.
Formally uncharged two-coordinate tellurium atoms in trialkyl(telluroseleno)phosphonium salts [(tBu2iPrPSeTe-p-Tol)+ (p-TolTeI2)-] () and {[(iPr3PSeTeI)+]2 (TeI6)2-} () behave as soft acceptors towards iodotellurate anions, thus exhibiting a novel type of Te...Te anion-->cation donor-acceptor interaction () and a chelating TeIV(micro-I)2TeII anion-cation coordination () in the solid state.
