新的有机无机化合物[C8 H10 NO] 2CdCl 4在室温下属于正交晶系（CmCaspace族），晶胞参数为：a= 19.9803（5）B= 15.3829（3），c= 13.8168（3），Z = 8.原子排列可以描述为有机/无机层沿沿着方向的交替。有机层由一种类型的[C8 H10 NO]+阳离子组成，无机层由孤立和扭曲的四面体CdCl 42 −阴离子组成。TGA-DTA曲线显示两个吸热峰。第一峰值可能是由于相变，而第二峰值对应于分解点。此外，在几个频率下对介电常数ε′和ε″随温度的变化的分析表明，可能是由于晶格中的无序引起的弛豫过程。
The new organic inorganic compound [C8H10NO]2CdCl4crystallizes at room temperature in the orthorhombic system (CmCaspace group) with the following unit cell parameters:a= 19.9803(5) Å,b= 15.3829(3) Å,c= 13.8168(3) Å andZ= 8. The atomic arrangement can be described as an alternation of organic/inorganic layers along theadirection. The organic layer is built up by one type of [C8H10NO]+cation and the inorganic layer is built up by isolated and distorted tetrahedral CdCl42−anions. The TGA–DTA curves revealed two endothermic peaks. The first peak may be due to a phase transition, while the second peak corresponds to the decomposition point. Additionally analysis of the dielectric constantsε′ andε″ versus temperature at several frequencies shows a relaxation process which could be due to disorder in the lattice.
