摘　　要：合成了一种新型的四氮杂取代的三环结构冠醚4,13-二氧-1,7,10,16-四氮杂三环[14.2.1.17,10]二十烷(L7),低温条件下在乙醚中培养出其单晶,用X射线衍射法测定了晶体结构.该晶体属单斜晶系,空间群P21/n,晶胞参数a=0.8984(7)nm,b=1.0805(9)nm,c=1.1040(9)nm;Z=2,β=111.707(13)°;V=0.9958(14)nm3,Dc=1.189g/cm3,μ=0.092mm-1,F(000)=392,R1=0.0649,wR2=0.1714.制备了配体L7与金属盐的配合物,分析结果表明,配体L7与金属离子形成1∶1型的配合物.A novel tricyclic tetraaza-substituted 18-crown-6 ligand has been synthesized. The crystal structure of the ligand was determined by X-ray diffraction method. It belongs to monoclinic crystal system with space group P2(1)/n, and a=0.8984(7) nm, b=1.0805(9) nm, c=1.1040(9) nm, Z=2, beta= 111.707(13)degrees, V=0.9958(14) nm(3), D-c=1.189 g/cm(3),mu=0.092 mm(-1), F(000)=392, R-1=0.0649, wR(2)=0.1714. The complexes of this ligand with transition metal ions have been prepared and characterized. The results show that the ligand can form 1:1 complexes with metal ions Cu2+, Zn2+, Co2+ and Mn2+.
