文摘

New homoleptic diphosphanylamido compounds of the lanthanides, [Ln{N(PPh₂)₂}₃] (Ln = Sm, Gd, Dy), were synthesized and characterized by single crystal X-ray diffraction in the solid state and partly by NMR in solution. In the solid state the complexes solely show a η²-coordination of the {(Ph₂P)₂N}⁻ ligand. The dependence of the Ln–N and the Ln–P bond distance on the ion radius of the center metal was investigated.
