合成了一种新型的三环氮杂冠醚 4,13 二氧 1,7,10 ,16 四氮 1,16 :7,10 双亚乙基 9,18 二乙酸环十八烷 8,17 二酮 (C2 0 H3 2 N4 O8) ,在无水乙醇 -氯仿混合溶剂中培养出单晶 ,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P2 1/c ,晶胞参数a =0 87474(17)nm ,b =1 396 7(3)nm ,c =0 9430 9(19)nm ;β =111 18(3)°;Z =4,V =1 0 744 (4 )nm3 ,Dc=1 4 11g/cm3 ,μ =0 110mm-1,F(0 0 0 ) =488,R1=0 0 6 78,wR2 =0 185 0 .
A novel tricyclic azacrown ether 4,13-dioxa-1,7,10,16-tetraaza-1,16:7,10-bis(ethylene)-9,18-diacetic acid cyclooctadecane-8,17-dione has been prepared. The crystal structure of the compound was determined by X-ray diffraction method. It belongs to monoclinic crystal system, space group P2(1)/c with a = 0.87474(17) nm, b = 1.3967(3) nm, c = 0.94309(19) nm; beta = 111.18(3)degrees; Z = 4, V = 1.0744(4) nm(3), D-c = 1.411 g/cm(3), mu = 0.110 mm(-1), F(000) = 488, R-1 = 0.0678, wR(2) = 0.1850.
