Crystal Structure of Bis｛1-(2-methoxyethyl)indenyl｝dysprosium Chloride

The title complex bis｛1 (2 methoxyethyl)indenyl｝dysprosium chloride ((CH 3OCH 2CH 2C 9H 6) 2DyCl, M r =544.42) crystallizes in the triclinic,space group P 1(No.2) with unit cell parameters a = 10.326(1), b = 10.591(1), c = 20.256(3) , α = 91.543(9), β = 97.69(1), γ = 94.754(9)°, V=2186.2(9)  3, Z = 4, F(000)=1076, D C= 1.65g/cm 3, μ =35.87cm -1, R =0.042 and R w =0.051 for 6193 observed reflections with I>3σ(I ). X ray crystal structure study shows there are two crystallographically independent molecules A and B (A=(CH 3OCH 2CH 2C 9H 6) 2 Dy(1) Cl, B=(CH 3OCH 2CH 2C 9H 6) 2Dy(2)Cl) in an asymmetric unit of the title complex. Each molecule was unsolvated monomeric molecule with a trans arrangement of both the sidearms and indenyl rings.
