摘要
研究了Cu(OAc)2·H2O与两个Schiff碱[水杨醛缩邻氨基吡啶(HSAPy)、水杨醛缩邻氨基苯酚(H2SAP)]在室温下的固相化学反应,用元素分析、XRD、DTA、UV漫反射和磁化率测定等方法表征了固相产物,其组成分别为Cu(SAPy)2和Cu(SAP),后者为双核结构.通过等温电导法得到固相反应的活化能为:H2SAP(35.25KJ/mol<HSAPy82.31KJ/mol,并初步讨论了配体的结构对固相反应的影响。
The solid state reactions of Cu(Oac)2,H2O with two schiff bases:o-[(o-hydroxybenzylidene)amino] pyridine(HSAPy)and o-[(o-hydroxybenzylidene)amino ] phenol (H2SAP) have been investigated at room temperature.The solid products were characterized by means of elemental analysis, XRD, DTA, UV and magnetic susceptibility. The activation energies,obtained by employing isothermal electrical conductivity method,increase in the order:H2SAP(35. 25KJ/mol<HSAPy(82. 31KJ/mol).The effect of the structures of ligands on the solid state reaction is discussed.
