| 摘 要： | <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.

| Abstract: | 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. |
