摘要
Rare earth complex(C 5H 9C 9H 6) 3SmCl -Li +(THF) 4(Ⅰ) was synthesized by reacting anhydrous SmCl 3 with two equivalents of C 5H 9C 9H 6Li. From mix solvent of THF and hexane, red color single crystals were obtained. The crystal belongs to a cubic system, space group P 2 13 with unit cell parameters a=b=c =1.754 0(2) nm, α=β=γ =90°, V =5.396 4(11) nm 3, 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.
