杂环偶氮化合物广泛应用于分析化学.它们与几十种金属离子形成高灵敏度的有色化合物.2-(2’-噻唑偶氮)-5-二乙胺基酚(1)是光度法测定铵、锆等的优良试剂和络合滴定指示剂.本文报道2-(2’-噻唑偶氮)-5-二乙胺基酚铜(Ⅱ)螯合物晶体结构的测定. 实验取一定量1溶于氯仿,加适量氯化铜水溶液后分成两相,加10mL pH5的醋酸钠缓冲液,再加乙醇,使两相混为一相.然后滴加水,使溶液又分成两相,氯仿相用无水Na_2SO_4干燥,溶液在真空干燥器中抽除氯仿后析出1的铜(Ⅱ)螯合物的紫红色晶体. 我们使用Syntex P3/R3四圆衍射仪收集强度数据.采用Mo K_a射线经石墨单色 Heterocyclic azo compounds are widely used in analytical chemistry. They form highly sensitive colored compounds with dozens of metal ions. Spectrophotometric determination of 2- (2’-thiazolylazo) -5-diethylaminophenol (1) Ammonium, Zirconium, etc. The crystal structure of 2- (2’-thiazolylazo) -5-diethylaminophenol copper (II) chelate was reported in this paper.The experiment took a certain amount of 1 dissolved in chloroform, add appropriate amount of aqueous copper chloride solution into two phases, add 10mL pH5 sodium acetate buffer, plus ethanol, so that the two phases into one phase, then add water, the solution is divided into two phases, the chloroform phase After drying with anhydrous Na 2 SO 4, the solution precipitated purple crystal of copper (II) chelate complex 1 after chloroform was removed from the vacuum desiccator.We collected the intensity data using Syntex P3 / R3 four-circle diffractometer.Using Mo K_a radiation Graphite monochrome
