Complex Cp’2 ErCl(Cp’=2-methoxyethylcyelopentadienyl)(I)has been synthesized by the reaction of Cp’ Na and ErCl3 in THF It crystallizes in space group Pnma with a=12.269(0),b=11.742(6),c=11.197(2)A,V=1613.1A3,Dc=1.849 g/cm3,Z=4,A=0.71073 A,μ(MoKa)=54.38 cm-1,F(000)=876,R=0.043,Rw=0.046.The Er atom is formally nine-coordinated with a pseudo-trigonal bipyramidal geometry with the “equatorial” plane composed of the Er atom,the Cl atom and the centers(1)and(2)of the two Cp rings(Cp=cy-clopentadienyl).The molecule is located at the crystallographic mirror plane through the atom C(3),C(4),C(S),Er,O(1)and C(6).The atom Cl and the atoms of Cp’(2)(except C(16)and C(16’))are disordered with an occupancy of 0.5 each.
