(C5H9C5H4)(3)NdBrLi(THF)(4)(1)(C5H9=cyclopentyl)
was obtained from the reaction of NdCl3 with C5H9C5H4Na and LiBr
(Nd:Na:Li=1:2:1 molar ratio) in THE X-ray crystallography showed that the
ten-coordinated neodymium atom is bonded to three cyclopentylcyclopentadienyl(eta(5))
rings and a single bromine atom bridging a lithium which is bonded to three THF
molecules. Complex 1 is triclinic, P1 space group with unit dimensions of a=
12.048(2), b= 13.498(3), c= 13.831(3)Angstrom, a = 104.16(3), beta = 104.07(3),
gamma =95.96(3)degrees, V=2083.3(7)Angstrom(3), Z=2, D-c=1.35Mg/m(3) and
F(000)=874. (C5H9C5H4)(3)SmTHF (2) was synthesized by reaction of anhydrous
SmCl3 with C5H9C5H4Na at a molar ratio of 1:3. The structure was determined by
X-ray crystallography. The ten-coordinated samarium atom is bonded to three
cycloperrtylcyclopentadienyl rings and one oxygen of THF molecule to form a
pseudo-tetrahedron. Complex 2 is orthorhombic, Fdd2 space group with unit cell
dimensions of a =28.175(5)Angstrom, b =46.24(2) Angstrom, c =9.167(4)
Angstrom(3), V=11943(8)Angstrom(3), Z= 16, D-c = 1.38Mg/m(3) and F(000)=5136
