| Abstract: | (C5H5)2Lu(μ-Cl2)Na(dme)2 reacts with LiSi(CH3)3 in dimethoxyethane with formation of Li(dme)3](C5H5)2Lu(Si(CH3)3)2]. The crystal structure study shows the compound to consist of discrete ions Li(dme)3]+ and (C5H5)2Lu(Si(CH3)3)2]?. The compound crystallizes in the space group P2/n with a 14.497(5) b 9.041(2), c 14.672(6) Å, β 103.85(3)° and V 1867(2) Å3. The crystal and molecular structure was refined to R = 0.0473 for 2491 observed reflections with Fo  3σ(Fo). |
