摘要
以四水合钼酸铵〔(NH4)6Mo7O24.4H2O〕、磷酸和2-氨基-4-甲基吡啶(AP)为原料,按一定比例在180℃恒温水热法反应5 d,合成了超分子化合物(APH)2(H4P2Mo5O23).2H2O,收率为80%。用红外光谱、紫外可见光谱、氢核磁共振谱、X射线粉末衍射和TG-DTA对产物进行了表征。结果表明,杂多阴离子保持结构不变,而有机阳离子红外和紫外光谱发生了蓝移,有机阳离子和杂多阴离子以静电力和氢键作用形成了超分子化合物。
Supramolecular compound (APH)2 (H4P2Mo5O23) · 2H2O was synthesized from ( NH4 ) 6Mo7O24· 4H2O, H3PO4 and 2-amino-4-picoline(AP) in 80% yield using hydrothermal method after reacting at 180 ℃ for 5 days. The product was characterized by FTIR,UV, ^1HNMR,XRD and TG - DTA. It is shown that the heteropolyanions remain unchanged, while the organic cations exhibit blue shift in IR and UV spectra. The supramolecular compound was formed by organic cations and heteropolyanions through hydrogen bonds and electrostatic forces.
