摘要
在非水溶剂中合成了3种基于1-苯基-3-甲基-4-萘乙酰基-5-吡唑啉酮(PMNAP)缩胺类新型席夫碱及其铜配合物。由元素分析、络合滴定法、质谱和摩尔电导值推测出配合物的组成为CuL2[L=L1,L2,L3],通过红外光谱、紫外光谱、热重分析和核磁共振氢谱对配体和配合物进行了结构表征。结果表明:在测试条件下,3种新配体均以酮式和烯醇式结构共存,配位时酮式可能转化为烯醇式结构按去质子的方式以烯醇负离子的O和亚胺基上的N与铜中心离子配位,配合物的配位数均为4。
In this paper,three novel Schiff base ligands derived from 1-phenyl-3-methyl-4-naphtho-acetyl-5- pyrazolone（PMNAP） and amine,and their copper complexes have been synthesized in the nonaqueous solvent. The formula of complexes is CuL2 [L= L1 , L2 , L3] based on elemental analysis, complexometric titration, MS and molar conductance value. Their molecular structures are characterized by IR, UV, TG and 1 HNMR. The resuits of structural characterization show that three novel ligands all coexist in ketoform and enolform structure under the measuring condition, the former may change into the latter after coordination and bonds with copper central ion by O of enolic negative ion losing the proton and N atom of imdo group. The coordination number of three complexes is four.
