| 摘要: 合成了2个新的希土冠醚配合物Ln(NO3)3·C26H38N2O4(Ln=La、Ce; C26H38N2O4=1, 7, 10, 16-四氧-4，13-二氮杂-N，N′-二苄基环十八烷)。通过元素分析，红外光谱，拉曼光谱及其 1H核磁共振谱进行表征。用四圆衍射仪测定了La(NO3)3·C26H38N2O4·CH3CN的晶体结构。晶体属三斜晶系，P1空间群，晶胞参数：a=1.2869(4) nm, b=1.5868(6) nm, c=0.9147(2) nm; α=101.89(2)°, β=105.38(2)°, γ=71.96(3)°; Z=2。dcald.=1.58 g·cm-3, μ(MoKα)=13.25 cm-1。中心镧离子与冠醚配体中的4个氧原子和2个氮原子配位，3个硝酸根中的6个氧原子也与La3+配位，形成配位数为12的配合物。 |

| Abstract: Two novel rare earth crown ether complexes Ln(NO3)3·C26H38N2O4(Ln=La、Ce; C26H38N2O4=1, 7, 10, 16-tetraoxa-4, 13-diaza-N,N′-dibenzylcyclooctadecane) were synthesized and characterized by elemental analysis, IR, Raman and 1H NMR spectral data. The crystal structure of La(NO3)3·C26H38N2O4·CH3CN was determined by X-ray analysis. The crystal crystallizes in triclinic, space group P1 with cell dimensions: a=1.2869(4) nm, b=1.5868(6) nm, c=0.9147(2) nm; α=101.89(2)°, β=105.38(2)°, γ=71.96(3)° and Z=2. The central lanthanum atom is bonded to 4 oxygen atoms and 2 nitrogen atoms from the crown ether, and 6 oxygen atoms of the bidentate nitrate groups, forming a complex with coordination number 12. |
