Abstract The reaction of 4-amino-5-ethyl-2H-1,2,4-triazole-3(4H)-thione (AETT, L1) with 2-thiophen carbaldehyde in methanol leads to the corresponding Schiff-base HL1a. The reaction of L1 with AgNO3 in ethanol gives the ionic complex [[Ag(L1)]NO3}2]n (1). The ionic complex [(PPh3)2Ag(HL1a)2]NO3 · CH3CN (2) can be obtained by the reaction of HL1a with [(PPh3)2Ag]NO3 in methanol and acetonitrile solution
摘要4-氨基-5-乙基-2H-1,2,4-三唑-3(4H)-硫酮(AETT,L1)与2-噻吩甲醛在甲醇中的反应生成相应的席夫碱HL1a。L1与AgNO3在乙醇中的反应得到离子络合物[[[Ag(L1)] NO3} 2] n(1)。离子络合物[(PPh3)2Ag(HL1a)2] NO3·CH3CN(2)可通过在甲醇和乙腈溶液中使HL1a与[(PPh3)2Ag] NO3反应,同时与[(PPh3)2PdCl2反应)得到。在乙酸钠在甲醇中的存在下会生成中性络合物[(PPh3)2Pd(L1a)2]·4MeOH(3)。所有化合物均通过红外光谱,元素分析以及X射线衍射研究进行了表征。
