摘　　要：合成了配合物[Cu(Ⅱ)(2L)(5H2O)(SO4)](L为二氰二胺),通过元素分析、原子吸收光谱、NMR、IR、UV对配合物进行了表征。结果表明Cu()与两分子二氰二胺中的腈基和胍基氮配位形成了四配位的双六元环结构。稳定性分析表明,易成键的dsp2杂化轨道,大π键π99及双六元环结构均增强了配合物的稳定性。The Cu（Ⅱ ） complex[Cu（ Ⅱ ）（2L）（5H2O）（SO4）] was synthesized and characterized by EA, Atomic Absorption spectrometry,NMR, IR and UV, where L is dicyandiamide. As can be seen from the result, the complex has four-coordinate double-six-member-ring structure, in which the central ion Cu （ Ⅱ ） coordinates with two cyano nitrogens and two guanidino nitrogens of two L molecules. The stability analysis shows that the readily-bonding dsp^2 hybrid orbitals, the formation of big π bond π9^9 and the double-six-member-ring structure all increase the stability of the complex.
