| Abstract: | The complex [(ButC5H'4)2YbCl]2, crystallized in the triclinic system,space group P1, with a=8. 392(3), b=9. 402(3), c=12. 418(5) , a=68. 78(3),P= 77. 43(3), γ=86. 41 (3)°, V= 891. 4(5) , Z=1, Dc= 1. 68 g/cm3, Mr=901. 79, λ=0. 71069, F(000) = 464, μ= 56. 49 cm-1. T= 298 K. Final R=0.073, Rw= 0.081 for 2214 reflections with I> 3σ(I0). The molecule has a dimerstructure with two asymmetrical chlorine bridges. Two Bu5C5H4 and two chlorineatoms around the central atom Yb form a distorted tetrahedral geometry. |
