摘要: 2-硝基苯甲醛与异烟肼在无水乙醇中反应合成了1种异烟酰腙化合物C13H10N4O3并培养了单晶,采用X-射线单晶衍射法测定了其晶体结构,结果表明,它的一水合物C13H10N4O3·H2O (1)的晶体属正交晶系,空间群Pna21,晶胞参数:a=1.569 9(4) nm,b=0.716 12(17) nm,c=1.139 9(3) nm,V=1.281 5(5) nm3,Z=4,Mr=288.27,Dc=1.494 g·cm-3,F(000)=600。采用常规溶液挥发法制备了该酰腙的镉配合物[Cd(H2O)4(C13H10N4O3)2](NO3)2 (2),化合物1的晶体属单斜晶系,空间群P21/n,晶胞参数:a=0.782 48(13) nm,b=1.739 8(3) nm,c=1.208 0(2) nm,β=98.570(3)°,V=1.626.2(5) nm3,Z=2,Mr=848.99,Dc=1.734 g·cm-3,F(000)=860。同时,化合物经元素分析、红外光谱、紫外光谱和热重分析进行了表征。初步测试了二者的体外抗癌活性,结果表明2对人结肠癌细胞SW620有较强的增殖抑制作用。 | |||||||||||||

Abstract: An isonicotinoyl hydrazone Schiff base monohydrate, C13H10N4O3·H2O (1), was synthesized by rection of 2-nitrobenzaldehyde and isoniazide, and its cadmium(Ⅱ) complex [Cd(H2O)4(C13H10N4O3)2](NO3)2 (2) was prepared. They have been characterized by elemental analysis, IR, UV-Vis, TGA and X-ray diffraction single crystal analysis and result showed that the crystal of 1 belongs to the orthorhombic system,space group Pna21 with cell parameters a=1.569 9(4) nm, b=0.716 12(17) nm, c=1.139 9(3) nm, V=1.281 5(5) nm3, Z=4, Mr=288.27, Dc=1.494 g·cm-3, F(000)=600 and the crystal of 2 belongs to the monoclinic system,space group P21/n with cell parameters a=0.782 48(13) nm, b=1.739 8(3) nm, c=1.208 0(2) nm, β=98.570(3)°, V=1.626.2(5) nm3, Z=2, Mr=848.99, Dc=1.734 g·cm-3, F(000)=860. The compound 2 displayed strong in vitro anti-tumor activity against SW620 cells.CCDC: 932233, 1; 932234, 2. | |||||||||||||
