| 摘 要： | <正> The title complex was prepared from the reaction of NdClLi0.3 and C8H8, its crystal structure was determined by single-crystal X-ray diffraction. It crystallizes in the monoclinic space group P21/c with cell dimensions o = 11. 819(3), 6=12.651(3), c=13. 478(3)A, β=122.99(2)°, Mr = 856. 00, Z = 2, Dc=1. 68g/cm3, F(000) = 636. 89, V = 1690. 33A3. The structure was solved by direct methods and Fourier techniques. Least squares refinement on the basis of 1842 observed reflections led to final R = 0. 038 and Rw = 0. 040. The molecule is a dimer of C3H8NdCl(THF)2 bridged by two Cl atoms with Nd -Cl bond lengths of 2. 832(2) A and 2. 917(3)A. |

| Abstract: | The title complex was prepared from the reaction of NdClLi0.3 and C8H8, its crystal structure was determined by single-crystal X-ray diffraction. It crystallizes in the monoclinic space group P21/c with cell dimensions o = 11. 819(3), 6=12.651(3), c=13. 478(3)A, β=122.99(2)°, Mr = 856. 00, Z = 2, Dc=1. 68g/cm3, F(000) = 636. 89, V = 1690. 33A3. The structure was solved by direct methods and Fourier techniques. Least squares refinement on the basis of 1842 observed reflections led to final R = 0. 038 and Rw = 0. 040. The molecule is a dimer of C3H8NdCl(THF)2 bridged by two Cl atoms with Nd -Cl bond lengths of 2. 832(2) A and 2. 917(3)A. |
