Metallorganische verbindungen der lanthanoide: LVI. Synthese und röntgenstrukturanalyse von [Li(THF)4][(C5H5)2Lu(NPh2)2]

Cp2Sm(μ-CH3)2Li(tmed) reacts with HNPh2 to give [Li(tmed)2][Cp2Sm(NPh2)2]. The structure of the corresponding Lu derivative, prepared in tetrahydrofuran, [Li(THF)4][Cp2Lu(NPh2)2] has been determined by an X-ray diffraction study. The crystals are triclinic, space group P1, with a 1418.8(8), b 1512.7(6), c 1301.6(4) pm, α 114.68(3), β 99.85(3), γ 76.55(4)°, Z = 2, R = 0.0746 for 8535 observed data (I ⩾ 6σ(I)).
