Three new organic–inorganic hybrid compounds based on [SiNb12V2O42]12− have been obtained under hydrothermal conditions and characterized by IR, XRD, and single crystal X-ray diffraction analysis. Single crystal X-ray analysis reveals that [Cu(en)2]4[Cu(en)2(H2O)2]2[SiNb12V2O42]·14H2O (1) is constructed from [SiNb12V2O42]12− and two kinds of copper complexes, polyoxoanions in [Cu(en)2]2[Cu(en)2(H2O)]4[SiNb12V2O42]·4H2O (2) and [Cu(en)2(H2O)2]4[Cu(en)2(H2O)]2[SiNb12V2O42]·11H2O (3) are identical to compound 1, but the copper complex combinations of these two compounds are different from that of compound 1. Therefore, the final structures of the three are different from one another. All the three compounds are excellent catalysts for the epoxidation of styrene. In addition, we also synthesized an isopolyniobate K6H2Nb6O19·17H2O (4), which exhibits a 3-D structure constructed from [Nb6O19]8− and potassium clusters.

基于[SiNb 12 V 2 O 42 ] 12−的新型有机-无机杂化化合物,对苯乙烯环氧化具有高催化活性

在水热条件下获得了三种基于[SiNb 12 V 2 O 42 ] 12−的有机-无机杂化化合物,并通过IR,XRD和单晶X射线衍射分析对其进行了表征。单晶X射线分析表明,[Cu(en)2 ] 4 [Cu(en)2(H 2 O)2 ] 2 [SiNb 12 V 2 O 42 ]·14H 2 O(1)由[SiNb 12 V 2 O 42 ] 12−和两种铜络合物,[Cu(en)2 ] 2 [Cu(en)2(H 2 O)] 4 [SiNb 12 V 2 O 42 ]·4H 2 O(2)和[Cu(en )2(H 2 O)2 ] 4 [Cu(en)2(H 2 O)] 2 [SiNb 12 V 2 O 42 ]·11H 2 O(3)与化合物1相同,但是这两种化合物的铜络合物组合与化合物1不同。因此,这三个的最终结构彼此不同。这三种化合物都是苯乙烯环氧化的极佳催化剂。此外,我们还合成了异聚铌酸钾K 6 H 2 Nb 6 O 19 ·17H 2 O(4),它表现出由[Nb 6 O 19 ] 8-和钾簇构成的3-D结构。
