Abstract: The reaction of Me4Si2(C5H4)2Na2with LnCl3in THF leads to the formation of Me4Si2(C5H4)2LnCl(Ln: Nd(3), Sm(4), Gd(5),Y(6))or Me4Si2(C5H4)2Ln(C5H5)(THF)n Ln: La(1) n=1, Pr(2) n=0); complex 4 was recrystallized in THFto form [Me4Si2·(C5H4)2Sm(μ-Cl)(THF)]2in space group P21/c with a=1. 2982(3) nm,b=1. 2269(3)nm,=1.3681(2) nm,β=96.79(2)°,Z=2,R=0.068.
