摘要: 室温或近室温条件下,2-氨基嘧啶(AP)与4种铜(Ⅱ)盐CuCl2·2H2O、CuBr2、CuSO4·5H2O、CuAc2·H2O发生固-固相化学反应,生成3类不同配位比(Cu/AP分别为2:2、1:1和1:2)的2-氨基嘧啶合铜配合物。用元素分析、碘量法、电感耦合等离子直读光谱(ICP)、IR、XRD、UV、ESR等方法表征了固相反应产物。不同阴离子铜盐的结构是影响固相反应的主要原因。讨论了固相反应的过程。反应沿晶格结构变化最小(活化能最低)的途径进行。

Abstract: The solid state reactions of 2-aminopyrimidine(AP)with CuCl2·2H2O,CuBr2,CuSO4·5H2O and CuAc2·H2O at room or near room temperature result in the formation of three kinds of complexes with coordination ratio Cu/AP=1:2,1:1 and 2:1 respectively. The solid products were chracterized by elemental analysis,XRD,ICP, UV, ESR methods. The mechanism of this kind of reations and the effects of copper and the reagents were discussed.
