摘要
以Na_2WO_4·2H_2O、NH_4VO_3和4,4'-联吡啶(4,4'-bpy)为反应物、采用水热法合成多酸化合物(C_(10)H_(10)N_2)_2VW_(12)O_40·H_2O.用红外光谱、X-射线衍射和X-射线单晶衍射仪测定其晶体结构.该化合物是由Keggin结构阴离子[VW_(12)O_40]_4-配合片段质子化的4,4'-bpy构成,二维层通过N—H…O、C—H…O、O—H…O氢键进一步桥连,形成无限延伸的三维结构.
Polyacid compound（C10H10N2）2VW12O40·H2O was synthesized by hydrothermal reaction of Na2WO4 ·2H2O, NH4VO3 and 4,4＇-bpy. Infrared spectroscopy and X-ray diffraction were employed to characterize the crystal structure of the product. The results showed that the compound is composed of anionic [ VW12O40]^4- with Keggin structure fragments and the protonized 4,4 ＇- bpy. Two-dimensional layer by N-H…O, C-H…O, O-H…O hydrogen bond bridged even further, forming the unlimited extension of the three-dimensional structure.
