摘要
室温或近室温条件下，２－氨基嘧啶（ＡＰ）与４种铜（Ⅱ）盐ＣｕＣｌ＿２·２Ｈ＿２Ｏ、ＣｕＢｒ＿２、ＣｕＳＯ＿４·５Ｈ＿２Ｏ、ＣｕＡｃ＿２·Ｈ＿２Ｏ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。
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 me-thods. The mechanism of this kind of reations and the effects of copper and the reagents were discussed.
