摘　　要：Reaction of DyCl 3 with excessive amount of K and indene in THF forms (C 9H 7) 3Dy(THF), which crystallizes in hexagonal system, space group P6 3 with a= b=11.719(5), c=10.167(2) , V=1211(1) 3, M r=580.07, D c =1 590 g/cm 3, Z=2, F(000)=578, μ =31.31 cm -1 . Final R =0.043 and R w =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 η 3+η 2 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) , respectively. The average Dy-C( η 3) bond distance is 2.66(1) .Reaction of DyCl 3 with excessive amount of K and indene in THF forms (C 9H 7) 3Dy(THF), which crystallizes in hexagonal system, space group P6 3 with a= b=11.719(5), c=10.167(2) , V=1211(1) 3, M r=580.07, D c =1 590 g/cm 3, Z=2, F(000)=578, μ =31.31 cm -1 .
