摘  要:利用苯妥英,二(3-氨基丙基)胺与醋酸铜反应合成了一种新的铜三元配合物[Cu(pht)2(bapa)](CH3OH)[Hpht:苯妥英(5, 5-Diphenylhydantion); bapa:二(3-氨基丙基)胺(bis(3-aminopropyl)amine)]。通过元素分析、红外光谱和X射线单晶衍射确定了其组成和结构。配合物属于三斜晶系,空间群为Pī。晶胞参数:a=0. 84190(10)nm,b=1. 37540(15) nm,c=1. 5622(2) nm,α=86. 038(3)°,β=82. 542(2)°,γ=83. 904(2)°;V=1. 7807(4)nm3,Mr=729. 32,Z=2,F(000)=766,Dc=1. 360 g/cm3,μ=0. 666 mm-1,R1=0. 0692,wR2=0. 1430。配合物中铜离子配位数为5,处于变形三角双锥配位环境中。测试了配合物、配体和铜盐的抑菌活性,结果表明,它们对4种细菌均有一定的活性。A new Cu (II)complex was synthesized by reaction of 5,5-diphenylimidazoline-2, 4-dione ( phenytoin, Hpht), bis ( 3-aminopropyl ) amine (bapa) and copper acetate. Its crystal structure was determined by single-crystal X-ray diffraction. The compound crystallizes in the triclinic system, space group Pi with a = 0. 84190 (10) nm, b = 1. 37540 ( 15 ) nm, c = 1. 5622 ( 2) nm. α =86.038(3) °,β = 82.542 (2)°,γ = 83.904 (2)°; V = 1. 7807 (4) nm^3, Mr = 729.32, g = 2, F ( 000 ) = 766, Dc = 1. 360 g/cm^3 ,μ = 0. 666 mm^-1 , the final R = 0.0685 and wR = 0. 1306. Cu (II) locates in a N5 coordination environment and forms a distorted trigonal-bipyramid. The complex was valued for its antimicrobial activity against some bacteria in vitro. It was found to be active against the four test bacterial organisms.
