Five-co-ordinate iridium(III) hydrides with hydride resonances at τ 60
Abstract
Some purple hydrides of the type [IrHCl2(PBu2tR)2](R = Me, Et, or Prn) are described for which the hydride ligands have the largest τ-values yet observed (ca. 60); the influence of bulky phosphines on products is discussed briefly.
