| Abstract: | Reaction of DyCl3 with excessive amount of K and indene in THF forms (C9H7)3Dy(THF), which crystallizes in hexagonal system, space group P63 with a= b=11.719(5), c=10.167(2)(A) , V=1211(1) (A)3, Mr=580.07, Dc=1.590 g/cm3, Z=2, F(000)=578, μ=31.31 cm-1. Final R=0.043 and Rw=0.055 for 1273 observed reflections with I>3σ(I). The crystal structure shows that in the title compound the indenyl group is bonded to dysprosium in an η3+η2-fashion, and is bent over the C(1) and C(3) axis by 12.7°. Its nodal carbon atoms C(4) and C(9) which are weakly bonded to the metal atom are at distances of 2.92(1) and 2.94(1)(A), respectively. The average Dy-C(η3) bond distance is 2.66(1)(A). |
