钒氧多酸桥联大环铜配合物的合成及其晶体结构

摘要

A novel macrocyclic copper(Ⅱ) complex,[ CuL]2[H2V10028]. 7H20(1,L=5,7,7,12,14,14-hexamethyl-l,4,8,11-etraazacyclotetradeca-4,11-diene),was synthesized by reaction of the copper(Ⅱ) complex[CuL](Cl04)2 with NH4VO3.The structure was characterized by IR, elemental analysis and X-ray single crystal diffraction. 1( CCDC : 1510831) belongs to monoclinic system, space group P2(1) with a = 11.512(3) (A), b = 18. 170(4)(A), c=14.534(3)(A), [β=102. 997 (4)°,V=2962. 3(11)(A)3 , Dc =1. 986 mg·cm-3 ,Z=2, μ=2.300 mm-1 , R1=0.0472, wR2 =0.118 2.%以大环铜配合物[CuL](ClO4)2(L=5,7,7,12,14,14-六甲基-1,4,8,11-四氮杂环十四-4,11-二烯)与NH4VO3反应合成了一个新的钒氧多酸桥联大环铜配合物[CuL]2[H2V10O28]·7H2O(1),其结构经IR,元素分析和X-射线单晶衍射表征.1(CCDC: 1510831)属单斜晶系,P2(1)空间群,晶胞参数a=11.512(3) (A), b=18.170(4) (A), c=14.534(3) (A), β=102.997(4)°, V=2 962.3(11)(A)3, Dc=1.986 mg·cm-3, Z=2, μ=2.300 mm-1, R1=0.047 2, wR2=0.118 2.
