摘要

在甲醇溶液中,5-氯水杨醛和8-羟基喹啉乙酰肼经缩合反应合成了新化合物--一水合(E)-N'-(5-氯-2-羟基苯亚甲基)-2-(8-羟基喹啉基)-乙酰肼Schiff碱(1),其结构经1H NMR,IR,元素分析和X-射线单晶衍射表征.1属正交晶系,P2_12_12_1空间群,晶胞参数:a=4.748(5) (A),b=15.818(14) (A),c=22.802(2) (A),α=β=γ=90.00 °,V=1 712.0(3) (A)~3,Z=4,Dc=1.450 g·cm~(-3),μ=0.253 mm~(-1),F(000) =776,R_1=0.072 5,wR_2=0.102.1通过氢键相互作用,连接成一维无限链结构.%(E)-N'-(5-chloro-2-hydroxybenzylidene)-2-(quinolin-8-yloxy) acetohydrazide monohydrate Schiff-base(1) was synthesized by the condensation reaction of 5-chloro-2-hydroxybenzaldehyde with 2-(quinolin-8-yloxy)acetohydrazide in methanol solution. The structure was characterized by ~1H NMR, IR, elemental analysis and X-ray single crystal diffraction analysis. 1 belongs to orthorhombic, space group P2_12_12_1 with a=4.748(5) (A), b=15.818(14) (A), c=22.802(2) (A), α=β=γ=90.00 °, V=1 712.0(3) (A)~3, Z=4, Dc=1.450 g·cm~(-3), μ=0.253 mm~(-1), F(000)=776, R_1=0.072 5, wR_2=0.102.1 has a one dimensional infinite chain structure forming via hydrogen bond.
