摘要
由水杨醛 1H 苯并三唑乙酰腙 (C1 5H1 3N5O2 ,SBTH)与稀土高氯酸盐在甲醇中合成了 7种新配合物。经化学分析、元素分析及摩尔电导率的测定确定它们的组成为 :RE(HL) 2 ClO4 (RE =Pr ,Nd ,Sm ,Eu ,Gd ,Tb ,Dy ;H2 L =SBTH)。通过IR、UV光谱及1 HNMR研究 ,说明了配体是以烯醇式羟基氧 ,去质子酚羟基氧和亚氨基氮与RE3+ 以一个五元环和一个六元环形成三齿配位的配合物。生物活性实验显示 ,该类配合物对霉菌。
Salicylaldehyde 1H benzotriazol 1 acetyl hydrazone(C 15 H 13 N 5 O 2 , H 2L,SBTH) and its seven complexes with lanthanide perchlorates RE(HL) 2 ClO 4 (RE=Pr,Nd,Sm,Eu,Gd,Tb and Dy) have been synthesized and confirmed by elemental analysis, chemical analysis and molar conductivity measurement. The IR, UV and 1 H NMR results indicate that the SBTH is bonded with RE 3+ via the carbonyl and phenol oxygen and imidogen nitrogen, forming a pentacyclic and hexacyclic tridentate complex. The complexes show a certain antibacterial activity against leaf mold , bacilli and actinomyceto .
