摘　　要：采用水热法合成了含混合配体的铜配合物[CuLPhen]n(HL=5-硝基间苯二甲酸,Phen=1,10-菲咯啉),其结构由单晶X射线晶体学确定。标题化合物在单斜空间群P21/c中结晶。标题化合物的晶体数据:C_(20)H_(11)N_(3)CuO_(6),Mr=106.57,a=10.6619(3),b=12.5760(4),c=13.0550(3)Å,α=90,β=95.463(3),γ=90°,V=1742.50(9)Å3,Z=4,T=293(2)K,Dc=1.726 g/cm3,μ(MoKα)=0.301 mm^(-1),F(000)=51.0,R=0.0380,wR=0.07,GOF=1.026。当用作超级电容器电极材料时,所制备的配合物具有高比电容、良好的循环稳定性和优良的倍率性能。具体来说,在1 mol/L KOH溶液中,最大比电容可达到225 F/g。在5 a/g电流密度下,5000次循环后比电容保持率为67.31%。A copper complex with mixed ligands,[CuLPhen]n(HL=5-Nitro-isophthalic acid,Phen=1,10-phenanthroline)was synthesized by a hydrothermal approach and its structure was determined by single-crystal X-ray crystallography.The title complex crystallizes in monoclinic space group P21/c with the crystal data:C_(20)H_(11)N_(3)CuO_(6),Mr=106.57,a=10.6619(3),b=12.5760(4),c=13.0550(3)Å,α=90,β=95.463(3),γ=90°,V=1742.50(9)Å3,Z=4,T=293(2)K,Dc=1.726 g/cm3,μ(MoKα)=0.301 mm^(-1),F(000)=51.0,R=0.0380,wR=0.0907,and GOF=1.026.When used as electrode materials of super-capacitor,the prepared complex showed high specific capacitance,good cycle stability and excellent rate performance.Specifically,the maximum specific capacitance could achieve 225 F/g in 1 mol/L KOH solution.At the current density of 5 A/g,the retention of specific capacitance was 67.31%after 5000 cycles.
