四氯合铜酸二乙铵的低热固相合成及其热色性

Organicinorganic hybridbis(diethylammonium)tetrachlorocuprate was synthesized by solid state synthesis at lowheating temperature.Thermochromism and the probability on solid state reactiom of the hybrid were investigated by IR,DSC,XRD,and(in situ)UVvisible spectra.Solid state synthesis has much higher yield (908%) than solution method (491%) and almost need not any solvent during reaction process.

溶剂对四氯合铜乙二胺结构和性能的影响

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.
