Abstract: A series of phosphonium bis(ylide) rare-earth complexes of the type Cp*M(byl)₂ (M=Sc, Y, Dy, Yb and Lu; byl=[Ph₂P(CH₂)₂]⁻) has been synthesised and in three cases (Dy, Yb and Lu) structurally characterised revealing realization alongside with the chelating coordination mode for byl, also, for the first time, the bridging mode in dimeric Dy-complex.
