摘要
分别以水和乙醇/水为溶剂,采用液相合成方法制备了有机-无机杂合物四氯合铜酸乙二铵([H3N(CH2)2NH3]CuCl4),通过X射线衍射(XRD)和差示扫描量热(DSC)等测试手段对其结构和性能进行了表征.结果表明,不同溶剂对产物[H3N(CH2)2NH3]CuCl4的晶体结构和固-固相变性能有明显的影响.在乙醇/水介质中,晶体具有较高的a轴择优生长取向,所得产物层状结构明显,具有较高的固-固相变焓.
Organic-inorganic hybrid compound ethylenediamine tetrachlorocuprate（[H3N（CH2）2NH3]CuCl4） were prepared by liquid phase technology respectively with water and ethanol/water as solvent.Their structure and performance were characterized by X-ray diffraction（XRD） and differential scanning calorimetry（DSC）.The results indicate that different solvent has significant influence on the crystal structure and property of solid-solid phase transition of the product [H3N（CH2）2NH3]CuCl4.In ethanol/water medium,the crystal show a preferred orientation along a-axis,and the product prepared in ethanol/water medium show significant layered structure and a higher solid-solid phase transition enthalpy values.
