Organometallic complexes of the Group 3A and lanthanoid metals containing M(µ-Cl)2Li bridging units; the X-ray structure of [Nd{η-[C5H3(SiMe3)2]}2(µ-Cl)2Li(thf)2](thf = tetrahydrofuran)

Abstract

The following organometal(III) complexes have been prepared and characterised: (a)[M{η-[C5H3(SiMe3)2]}2(µ-Cl)2Li(L)2][M = Sc, Y, La, Ce, Pr, Nd, or Yb, and L = tetrahydrofuran (thf): or M = Y or La, and L2= Me2NCH2CH2NMe2(tmeda); or M = Y or Nd, and L2= MeOCH2CH2OMe (dme)], (b)[MCl2 –n(OArMe)n(µ-Cl)2Li(thf)2](OArMe= OC6H2Bu2t-2,6-Me-4, M = Y, La, Er, or Yb, and n= 1; or M = Y and n= 2), and (c)[ErCl{N(SiMe3)2}(µ-Cl)2Li(thf)2]; the X-ray structure of the title compound shows that both the Nd and Li atoms are in a distorted ttetrahedral environment, and important molecular parameters include Nd–Clav. 2·744, Li–Clav 2·405, Nd … Li 3·63(3)Å, Cl–Nd–Cl′ 82·1, and Cl–Li–Cl′97.2(9)°
