| 摘 要： | 标题化合物的分子式为Eu(NO3)6]Eu(NO3)2C12H24O6]3。晶体属单斜晶系,空间群为C2/m,a=28.772(6),b=11.142(2),c=12.024(2)Å,β=112.63(2)°,Z=2。对1167个可观察反射(I≥3σ(I)),用块矩阵最小二乘法精修所有的结构参数,最后的一致性因子R=0.063。结构分析表明:晶体学上有三个不同的离子,(1)Eu(NO3)6]3-,(2)Eu(NO3)2C12H24O6]+(有序)和(3)Eu(NO3)2C12H24O6]+(无序)。前两个离子都具有C2h对称性。第三个离子是C1对称性,它有一个无序的冠醚环。在Fourier图上二个冠醚环叠加,它们的相互交错角为32°。

| Abstract: | The crystal and molecular structure of Eu(NO3)3]4(C12H24O6)3 have been deter-mined from single-crystal x-ray diffraction data. The complex crystallizes in the mono-clinic space group C2/m with Z=2.Lattice parameters are:a=28.772(6), b=11.142(2), c=12.024(2)Å, β=112.63(2)°.The structure was solved by Patterson and Fou-rier techniques and refined by least-squares techniques to R=0.063 for 1667 reflec-tions. The structure contains three crystallographically distinct ions in the ratio 1:1:2:(1)Eu(NO3)6]3- with C2h symmetry, (2)Eu(NO3)2(C12H24O6)]+ with the same symmetry, (3)Eu(NO3)2(C12H24O6)]+ with a disordered polyether on a C1 symmetry site.The two positions of the disordered polyether are staggered by 32°. |
