摘要
通过水热法合成了一例新颖的稀土钨多酸化合物H_(26)(C_(2)H_(8)N_(2)H_(2))K(H_(2)O)[K(H_(2)O)Nd_(8)(H_(2)O)_(2)(W_(3)O_(12))(SiW_(10)O_(38))_(4)]·18H_(2)O 1。该化合物的不对称单元由两个[SiW_(10)O_(38)]^(12-)通过一个{Nd_(4)(H_(2)O)^(12+)}结构单元和W_(3)O_(12)连接而成。化合物1簇阴离子通过K离子连接成一维无限链,再通过氢键连接成二维平面结构。针对该化合物,做了一系列表征,测试了其二维相关红外光谱,并对其作了详细分析,结果说明化合物1簇阴离子振动偶极矩对磁场和温度的变化均有响应峰,2D-IR COS提供了一种结构表征新方法。
In this article,a novel Ln-containing tungsten polyacid compound H_(26)(C_(2)H_(8)N_(2)H_(2))K(H_(2)O)[K(H_(2)O)Nd_(8)(H_(2)O)_(2)(W_(3)O_(12))(SiW_(10)O_(38))_(4)]·18H_(2)O1 was synthesized by hydrothermal method.The asymmetric unit of 1 is composed of two[SiW_(10)O_(38)]^(12-)connected by a{Nd_(4)(H_(2)O)^(12+)}structural unit and W3O12.The cluster anions of compound 1 are connected into one-dimensional infinite chains by K ions,and then connected into two-dimensional planar structures by hydrogen bonds.For this compound,a series of characterizations were made,and its two-dimensional correlation infrared spectrum was tested and analyzed in detail.The vibration dipole moment of compound 1 has response peaks to changes in magnetic field and temperature.2D-IR COS provides a new method for structural characterization.
