利用加热法合成了标题配合物[Cu(abpa)(pht)]pht.CH3OH(Hpht:苯妥英,即5,5-二苯基-2,2咪唑烷酮;abpa:(2-氨基乙基)-二(氨基丙基)胺),采用元素分析、红外光谱、热重分析、X-射线单晶衍射等技术对其结构进行了表征。该晶体属三斜晶系,P墿空间群,晶胞参数:a=0.8497(2)nm,b=1.4120(3)nm,c=1.7150(3)nm,α=67.544(2)°,β=87.434(3)°,γ=76.842(3)°;V=1.8496(6)nm3,Dc=1.387 mg/m3,Z=2,F(000)=814,μ=0.646mm-1,R1=0.0980,wR2=0.2180[I>2σ(I)]。每个配合物分子由一个(2-氨基乙基)-二(氨基丙基)胺苯妥英合Cu(II)阳离子、一个苯妥英阴离子及一个溶剂化甲醇分子构成;配合物中每个Cu(II)离子与来自一个苯妥英的1个N原子和一个(2-氨基乙基)-二(氨基丙基)胺的4个N原子配位,形成畸变的三角双锥结构单元。利用琼脂扩散法和单片滤纸法测试了配合物、配体和铜盐的抑菌活性,结果表明,它们对4种植物致病真菌和3种细菌均有一定的抑菌活性。
The title complex [Cu (abpa) (pht)] pht.CH3OH (Hpht: phenytoin, which is 5,5-diphenyl-2,2-imidazolidinone, abpa: (2-aminoethyl) - bis (aminopropyl) amine), its structure was characterized by elemental analysis, IR, TG, X-ray single crystal diffraction. The crystal belongs to the triclinic system, P 墿 space group with unit cell parameters of a = 0.8497 (2) nm, b = 1.4120 (3) nm, c = = 87.434 (3) °, γ = 76.842 (3) °; V = 1.8496 (6) nm3, Dc = 1.387 mg / 0.0980, wR2 = 0.2180 [I> 2σ (I)]. Each complex molecule consists of a (2-aminoethyl) -bis (aminopropyl) amine phenytoin Cu (II) cation, a phenytoan anion and a solvate methanol molecule; each Cu (II) The ions coordinate to one N atom from one phenytoin and to four N atoms from a (2-aminoethyl) -bis (aminopropyl) amine to form a distorted triangular bipyramid structural unit. The antibacterial activities of the complexes, ligands and copper salts were tested by agar diffusion method and monolithic filter paper method. The results showed that they had certain antibacterial activity against four kinds of phytopathogenic fungi and three kinds of bacteria.
