摘要
By X-ray (λ=0. 71069A) diffraction of single crystal,we have determined the crystal structure of C6H5GdCl2 (THF)4,C22H37Cl2O4Gd, MT=593. 2,or-thorhombic space group Ccm2;with lattice parameters a=12. 776(6),b=12. 954(6), c=15. 802(3)A ;V=2615. 4(1. 8)A3;Z=4,Dc=2. 43gcm-3,μ=29. 3cm-1,F(000) = 1120. The structure was solved by heavy-atom method and Fourier techniques and refined by least-squares to a final R=0. 051 ,Rw = 0. 049 for 839 reflections with I≥1. 5σ (I). The results revealed that the bond length of Gd-C is 2. 437(22) A ,the average bond lengths of Gd-Cl 2. 678(6) A ,Gd-O 2. 499(12) A, C-C from phenyl group 1. 376(40)A. This crystal structure is the first organolanthanide complex with only one Ln-C bond in the molecule.
