  SmCl₃ reacts with equimolar amounts of K[(S)-C₅H₄CHPhCH₂NMe₂] and Na[C₅Me₅] yielding [(S)-C₅H₄CHPhCH₂NMe₂](C₅Me₅)SmCl(1). The methylation of complex 1 with LiMe and the reactions of the known analogues of 1, [(S)-C₅H₄CHPhCH₂NMe₂](C₅Me₅)LnCl (Ln = Y (2), Lu (3)) with LiCH₂SiMe₃ afford [(S)-C₅H₄CHPhCH₂NMe₂](C₅Me₅)SmMe (4) and [(S)-C₅H₄CHPhCH₂NMe₂](C₅Me₅)LnCH₂SiMe₃ (Ln = Y (5), Lu (6)), respectively. The reactions of ScCl₃ and LuCl₃ with 1 equivalent of K[(S)-C₅H₄CHPhCH₂NMe₂] or K[C₅H₄CH₂CH₂NMe₂] followed by 2 equivalents of Me₃SiCH₂Li yield the complexes [(S)-C₅H₄CHPhCH₂NMe₂] Ln(CH₂SiMe₃)₂ (Ln = Sc (7a), Lu (7b)) or (C₅H₄CH₂CH₂NMe₂)Ln(CH₂SiMe₃)₂ (Ln = Sc (8a), Lu (8b)), respectively.

  The complexes Ln(Me(2)NC(2)H(4)Cp)(3) [Ln = Nd (2), La (3)] were synthesized by reaction of LnCl(3) with potassium cyclopentadienide 1 in tetrahydrofuran (THF) at room temperature (1:3 molar ratio), while the same reaction of lutetium(III) chloride yields the complex Lu(Me(2)NC(2)H(4)Cp)(2)Cl (4). These complexes sublime below 175 degrees C/10(-3) mm Hg. Single-crystal X-Ray structures performed for 2 and 3 reveal mononuclear structures. Crystals were obtained by slow evaporation of saturated n-hexane solutions (2: space group Pbca, orthorhombic, a = 1294.3(3) pm, b = 1711.8(1) pm, c = 4785.7(6) pm; V = 10603 x 10(6) pm(3); Z = 16; D = 1.385 g cm(-1); R = 0.055, RW = 0.058; 3: space group Cc, monoclinic, a = 1241.3(13), b = 2458.9(2), c = 859.0(3), beta = 98.85(2); V = 2590.6 X 10(6) pm(3); Z = 4; D = 1.404; R = 0.038, RW = 0.045). Structural details are explained in terms of the metal ionic radii of La-III and Nd-III, while in 2 the trivalent neodymium is coordinated by three eta(5)-cyclopentadienyl ligands and the nitrogen atom of one N-donor functionality (Nd-N2 2.73(1), Nd-N6 2.70(1) Angstrom), the larger lanthanum(III) centre of 3 is approached by a further nitrogen donor group (La-N2 2.898(6) Angstrom, La-N1 3.688(5) Angstrom).
