| 摘要: 通过[CuL]（ClO4）2（L=5，12-二甲基-1，8-二乙醇基-1，3，6，8，10，13-六氮杂环十四烷）与NH4VO3反应，得到一个钒氧多酸桥联大环铜配合物的三维配位聚合物{[CuL][VO3]2·0.67H2O}n。并对其进行了元素分析、红外光谱、紫外光谱、热重和X-射线单晶衍射测定。单晶结构测试结果表明配合物属于三方晶系，R3空间群。在晶体结构中，铜原子与大环配体上的4个氮原子和钒氧四面体[VO4]中的2个氧原子配位，形成畸变的八面体构型。钒氧多酸阴离子[V6O18]6-桥联大环配合物[CuL]2+形成一个具有一维通道的三维配位聚合物。 | |

| Abstract: Athree-dimensional transition metal copper macrocyclic complex {[CuL][VO3]2·0.67H2O}n (L=5,12-dimethyl-1,8-dihydroxyethyl-1,3,6,8,10,13-hexaazacyclotetradecane) has been isolated from the reactions of [CuL](ClO4)2 with NH4VO3, and structurally characterized by elemental analysis, IR, TG, UVspectrum and X-ray diffraction. The title compound crystallizes in the trigonal system, space group R3 with a=1.6877(12) nm, b=1.6877(12) nm, c=2.1630(3) nm, Mr=591.90, V=5.3354(10) nm3, Z=9, Dc=1.654 g·cm-3, F(000)=2739, μ=1.714 mm-1, the final R=0.0470 and wR=0.1347. The Cu(Ⅱ) atom lies on an inversion center and is octahedrally coordinated by four nitrogen atoms of the tetradentate macrocyclic Lligand in the equatorial plane and two oxygen atoms of [VO4] tetrahedrons in axial positions. The title compound shows a three-dimensional structure, which is constructed by the links of hexanuclear [V6O18]6- rings with [CuL]2+, forming one-dimensional channels occupied by guest water molecules.
