Organometallic Complexes of the Group 3A and Lanthanoid Metals containing M(μ-Cl)2Li Bridging Units; the X-Ray Structure of >2(μ-Cl)2Li(thf)2> (thf = tetrahydrofuran)

Article abstract of DOI:10.1039/c39810001191

The following organometal(III) complexes have been prepared and characterised: (a) >2(μ-Cl)2Li(L)2> 2 = Me2NCH2CH2NMe2 (tmeda); or M = Y or Nd, and L₂ = MeOCH2CH2OMe (dme)>, (b) 2-n(OAr^Me)_n(μ-Cl)2Li(thf)2> (OAr^Me = OC6H2Bu^t2-2,6-Me-4, M = Y, La, Er, or Yb, and n = 1; or M = Y and n = 2), and (c) (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 tetrahedral environment, and important molecular parameters include Nd-Cl_av. 2.744, Li-Cl_av. 2.405, Nd...Li 3.63(3) Angstroem, Cl-Nd-Cl' 82.1, and Cl-Li-Cl' 97.2(9) deg.
