两种新型噻唑类双席夫碱的合成及结构

摘要

Two thiazole bis-Schiff bases,thiazole-5-carbaldehyde-ethylenediamine(A)and thiazole-5-carbalde-hyde-1,2- diaminocyclohexane(B), were synthesized and characterized by UV-Vis spectra, IR,1H-NMR, and elemental analysis,and the crystal structure of B was obtained.According to X-ray single crystal diffraction,the B belongs to the monoclinic space group P2(l)/n with a = 11.091 (6)（A）,b= 17.821(10)（A）, 5.492(9)(A),β=92.97(6)°,V=3 058(3)(A)3 ,Z=8.%合成了两种新型噻唑类双席夫碱,5-噻唑醛缩乙二胺双席夫碱(A)和5-噻唑醛缩1,2-环已二胺双席夫碱(B),通过紫外-可见光谱、红外光谱、1H-NMR共振谱、元素分析对其进行了结构表征.培养得到了5-噻唑醛缩1,2-环己二胺晶体,经X-射线衍射测定,该化合物属单斜晶系,空间群为P2(1)/n,晶胞参数a=11.091(6)(A),b=17.821(10)A,5.492(9)A,β=92.97(6)°,V=305 8(3)A3,Z=8.
