The reaction of [(SiMe3)2NC(NC6H11)2]Li with SmCl3 in 2:1 molar ratio in THF gave bis(N,N-cyclohexyl-N创-bis(trimethylsilyl)samarium chloride, [(SiMe3)2NC(NC6H11)2]Sm(m- Cl)2Li(THF)2 1 in 85% isolated yield as pale-yellow crystals. Complex 1 was structurally characte- rized by single-crystal X-ray diffraction analysis at 289(2) K. It crystallizes in monoclinic, space group C2/c with a = 26.886(3), b = 13.677(2), c = 19.465(3) ? b = 120.26(1), V = 6182(2) ?, Z = 4, Mr = 1105.84, Dc = 1.188 g/cm3, F(000) = 2340 and m(MoKa) = 1.150 mm-1. The structure was refined to R = 0.0378 and wR = 0.0885 for 4342 observed reflections with I > 2s(I). The coordination geometry of samarium ion can be best described as a distorted pseudooctahedron.
