The coordination chemistry of <jats:bold>1<\/jats:bold> towards Rh<jats:sup>III<\/jats:sup> and Ir<jats:sup>III<\/jats:sup> was investigated and compared with the analogous 2,2\u2032\u2010bipyridine derivative, 2\u2010(2\u2032\u2010pyridyl)\u20104,6\u2010diphenylpyridine (<jats:bold>2<\/jats:bold>), which showed significant differences. The molecular structures of [RhCl(Cp*)(<jats:bold>1<\/jats:bold>)]Cl and [IrCl(Cp*)(<jats:bold>1<\/jats:bold>)]Cl (Cp*=pentamethylcyclopentadienyl) were determined by means of X\u2010ray diffraction and confirm the mononuclear nature of the <jats:italic>\u03bb<\/jats:italic><jats:sup>3<\/jats:sup>\u2010phosphinine\u2013Rh<jats:sup>III<\/jats:sup> and Ir<jats:sup>III<\/jats:sup> complexes.
