【摘要】为了更深入研究吡啶类希夫碱衍生物吡啶-3-甲醛缩4-氨基安替比林(L3)的配位形式及生物活性,以4-氨基安替比林、吡啶-3-甲醛和锌盐为原料,在温度为90℃条件下,以无水乙醇为溶剂,成功合成出了以L3为配体的一个锌配位聚合物([ZnBr2(L3)]n),晶体结构分析表明:配合物属于单斜晶系,空间群为P21/n,晶胞参数a=9.365 9(14),b=17.622(3),c=12.399 4(19),α=90°,β=107.700(3)°,γ=90°;V=1 949.6(5)3,Z=4,Dc=1.763Mg/m3,F(000)=1016,μ=5.371mm-1,R1=0.0321,wR2=0.0764[I>2σ(I)].通过元素分析、红外、热重、拉曼、X射线粉末衍射、荧光等测试手段对该锌(Ⅱ)配合物进行了结构表征及性质研究.更多还原

【Abstract】 In order to further research the structure and properties of Schiff base derivatives,we have synthesized one new Zn(Ⅱ)coordination polymer([ZnBr2(L3)]n(1)based on pyridine-3-carboxaldehyde-4-aminoantipyrine(L3)and reported its structure and spectral characterization by single-crystal X ray diffraction as well as IR,Raman,fluorescence,X ray powder diffraction,TG,and elemental analysis.Complex 1crystallizes in the monoclinic space group P21/n with cell parameters:a=9.3659(14),b=17.622(3),c=12.3994(19),α=90°,β=107.700(3)°,γ=90°;V=1949.6(5)3,Z=4,Dc=1.763 Mg/m3,F(000)=1016,μ=5.371mm-1,R1=0.0321,wR2=0.0764[I >2σ(I)].更多还原
