The crystal structure of the complex [Li(THF)4]2[{(η5-CH3C5H4)Nd-Cl(μ2-Cl)NdCl2(η5-CH3C5H4)}2(μ4-O)] has been determined by X-ray diffraction technique. The crystal is monoclinic of space group C2/c with a = 22. 740(7) ,b= 18. 319 (6),c=18. 330(6) A,β=93. 04(3)°,V = 7624. 93A3,Dc= 1. 55g/cm3,Z = 4,F(000) = 2800,μ=15. 02cm-1. The complex is consisted of two [Li(THF)4]+cations and one [{(η5-CH3C5H4)NdCl(μ2-Cl)NdCl2(η5-CH3C5H4)}2(μ4-O)]2-dianion. The two units [Cη5-CH3C5H4)NdCl(μ2-Cl)NdCl2(η5-CH3C5H4)] in the tetra nnclear-neodymium dianion are connected by a μ4-O bridge with the average Nd -μ4-O 2. 36(1) A ,Nd -C(ring) 2. 76(3)A,Nd-Cl 2. 823(7)A and Nd-μ2-Cl 2. 798(7)A.
