CRYSTAL STRUCTURE OF（η^5—C5H5）GdCl2（THF）3

<正> Compound (η5-C5H5)GdCl2(THF)3 was successfully prepared from action of GdCl3 and NaC5H5 in tetrahydrofuran (THF). X-ray diffraction data were collected at low temperature (about 210K). Its crystal belongs to the monoclinic space group P 21/n with a = 7. 821(2), b = 17.068(1), c=15. 057(1)(?), β=94. 76 (2)°, V = 2003. 2(10)(?)3, Z = 4, Dc=1. 69g/cm3, F(000)=1012, Mr=509. 6. The structure was solved by heavy-atom method. Least-squares refinement converged to a final R value of 0. 050. The coordination number of the Gd atom is 8. The centre of the cyclopentadienyl, the two Cl atoms and the three oxygen atoms of THF molecules form a distorted octahedron about the Gd atom.     

CRYSTAL STRUCTURE OF Fe4S4[SC（CH3）3]4[（C4H9）4N]2

<正> Fe_4S_4[SC(CH_3)_3]_4[(C1H_9)_2,Mr=1193. 23,tetragonal,142d,a = 23. 272(2), c= 13. 080(5) A ,V=7084(3) A3,Z=4,DC=1. 12g·cm-3,UUUU(MoKa) = 10. 8cm-1,F(000) = 2568,R=0. 058 for 1005 observed reflections. The cluster anion contains a cubane-type Fe4S4 core compressed along the 4 axis which is crystallographically imposed. Compared to other salts with different cations ,the core is subject to slight structural distortions in different crystalline environments and crystallographic symmetry of the anion is related to that of the cation.
