【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。更多还原

【Abstract】 A three-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 NH4 VO3,and structurally characterized by elemental analysis,IR,TG,UV spectrum and X-ray diffraction.The title compound crystallizes in the trigonal system,space group R3 with a=1.687 7(12) nm,b= 1.687 7(12) nm,c=2.163 0(3) nm,Mr =591.90,V=5.335 4(10) nm3,Z=9,Dc =1.654 g·cm-3,F(000)=2 739,μ=1.714 mm-1,the final R =0.047 0 and wR =0.134 7.The Cu(Ⅱ) atom lies on an inversion center and is octahedrally coordinated by four nitrogen atoms of the tetradentate macrocyclic L ligand 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.CCDC:902742.更多还原
