Abstract: Rare earth complex(C5H9C9H6)3SmCl-Li+(THF)4(Ⅰ) was synthesized by reacting anhydrous SmCl3 with two equivalents of C5H9C9H6Li. From mix solvent of THF and hexane, red color single crystals were obtained. The crystal belongs to a cubic system, space group P213 with unit cell parameters a=b=c =1.7540(2) nm, α=β=γ =90°, V =5.3964(11) nm3, Z =4. The ten-coordinated samarium atom is bonded to three cyclopentylindenyl rings and a chlorine atom to form the anionic part of the title complex, ring centroids and the chlorine atom form a tortured tetrahedron around samarium. In the cationic part, lithium atom coordinates to four oxygen atoms of THF molecules to form a normal tetrahedron. The Sm-C(within the same ring) distance varies from 0.268 to 0.299 nm.

Key words: Cyclopentylindene, Samarium, Rare earth complex
