| Abstract: | The reaction of YCl3 with two equivalent tBuMe2SiC5H4K in THF affords complex [(tBuMe2SiC5H4)2- YCl]2 which crystallizes in monoclinic, space group P21/c with a = 11.559(2), b = 14.132(3), c = 16.127(3) ? = 91.39(3), V = 2633.5(9) 3, Z = 2, Dc = 1.218 g/cm3, Mr = 966.13, m = 24.11cm-1 and F(000) = 1016. The least-squares refinement based on 5165 observed reflections (I > 2.0s(I)) converged to the final R = 0.0775 and Rw = 0.2107. The crystallographic data show that the title complex is a dichloride-bridged centrosymmetric dimmer. |
