| 2 | Synthesis and Crystal Structure ofTrichlorotetrakis(tetrahydrofuran) Europium显示文摘Crystal of EuCl3(C4H8O4). was obtained from the reaction of C9H7Naand EuCl3,(0. 8: 1 mole ratio) in THF. It was crystallized in Fdd2 space group withunit cell parameters a=29. 161 (4), b=16. 558(6), c=9. 479 (3) A, V=4577 (4)A3, Z=8, Dc= 1.59 g/cm3, Mr=546. 75. F(000)=2192, A(Mo Ka) =0. 71069, u=31. 12 cm-1, T=293K. The final R and Rw values are 0. 040 and 0. 051 respective-ly. Three chlorine atoms and four oxygen atoms from THF are coordinated with cen-tral europium ion to form a pentagonal bipyramid polyhedron with coordination number7, the average Eu-Cl; bond length is 2. 637 A and Eu-O 2. 460A. | KONG De-Yuan WANG Shao-Wu ZHU Qin XIE Yu-Yuan HUANG Xiao-Ying(Shanghai Institute of Materia Medica, the Chinese Academy of Sciences,Taiyuan road 294,Shanghai, 200031 ChinaDepartment of Chemistry, HongKong Chinese University, Shatin, HongkongState Key L | 1998 | Chinese Journal of Structural Chemistry1998，17，1： | 0 |
