用H3 BO3 ,NH4VO3 ,Cu(CH3 COO) 2 ·H2 O和乙二胺在水热条件下合成了新颖结构的多钒硼酸盐H3 {[Cu(en) 2 ] 5 [(VO) 1 2 O6B1 8O42 ] }[B(OH) 3 ] 2 ·16H2 O ,对其进行了单晶X射线衍射、红外光谱、拉曼光谱、紫外 -可见漫反射光谱、荧光光谱、顺磁共振谱和热重分析表征 .在该化合物的结构中 ,环状的B1 8O42 通过 18个B— ( μ3 O)—V键被两个V6O1 8簇夹在中间 ,簇阴离子 [(VO) 1 2 O6B1 8O42 ] 1 3 -分别通过 4个 [Cu(en) 2 ] 2 + 与邻近的簇阴离子靠静电相互作用连接成无限二维网状结构 ,其空洞尺寸为 0 619~ 1 817nm .
The novel structure of vanadyl borate H3 {[Cu (en) 2] 5 [(VO) 1 2) was synthesized under hydrothermal conditions with H3BO3, NH4VO3, Cu (CH3COO) 2 · H2O and ethylenediamine O6B1 8O42]} [B (OH) 3] 2 · 16H2O was prepared and characterized by single crystal X-ray diffraction, IR, Raman, UV- In the structure of this compound, the cyclic B1 8O42 is sandwiched by two V6O18 clusters through 18 B- (μ3O) -V bonds, and the cluster anions [(VO) 1 2 O6B1 8O42] 1 3 - are connected by two [Cu (en) 2] 2 + ions with adjacent cluster anions through electrostatic interactions to form an infinite two-dimensional network structure with a cavity size of 0 619 ~ 1 817 nm.
