Treatment of a κ 1 -P-monodentate bicyclic diphosphane iridium(III) complex with a labile gold(I) precursor afforded an unusual Ir III /Au I complex in which the P-P single bond has been cleaved. This reaction was cleanly reversed upon addition of tertiary phosphine. Carbon-carbon bond activation, across neighbouring P 2 C 2 N rings of the coordinated bicyclic diphosphane, occurred upon thermolysis of the Ir III /Au I complex.
