Abstract

Abstract: The crystal structure of .[Et₄N][Sm(S₂CNEt₂)₄] was determined by X-ray diffraction technique. The crystal crystallizes in monoclinic system, space group P2₁/n with a= 1.1695(3), b=2.0821(6), c=1.7420(7)nm, β=99. 79(3)°, Z=4, D_c= 1.39g/cm³, μ(Mo/KTσ) = 18.4cm^-1, F(000)=1812. The structure was solved by Patterson and Fourier techniques and refined by least-squares method to a final conventional Rof 0. 053 for 3116 (Ⅰ> 3σ-(Ⅰ)) reflections. Each asymmetric unit contains two ions [Sm (S₂CNEt₂)₄]^-1 and [Et₄N]⁺¹, having distance between central atoms N5 and Sm³⁺ to be 0.6522nm. The atom Sm is coordinated by eight sulphur atoms. The Sm-Sdistance lies in the range of 0.285-0.290nm with an average of 0.288nm.
