(L1) and polymer [Ag(L2)]n(NO3)n(H2O) for (L2). Crystal structure determination and Hirshfeld analysis reveal the presence of two important hydrogen bond interactions in the four compounds, O…H and H…N, involving nitrogen atoms of triazole ring. Contribution of these two types of hydrogen bonds evolves inversely from (L1) which contains one –OH, to (L2) containing two –OH, then to [Ag(L1)](NO3) dimer
摘要本工作描述了具有三唑部分的两个羟基席夫碱的合成,结构表征,Hirshfeld分析和抗菌测定:N-[(E)-(3-羟基)亚甲基] -4H-1-2-4三唑- 4-胺(L1)和N-[(E)-(2,4-二羟基)亚甲基] -4H-1-2-4三唑-4-胺(L2)。在第一配体(L1)和聚合物[Ag(L2)] n(NO3)n(H2O)的情况下,这两个席夫碱与AgNO3的相互作用导致Ag(I)二聚体[Ag(L1)](NO3) )(L2)。晶体结构的确定和Hirshfeld分析揭示了在四个化合物中存在两个重要的氢键相互作用,O…H和H…N,涉及三唑环的氮原子。这两种类型的氢键的贡献从包含一个-OH的(L1)到包含两个-OH的(L2)成反比。然后生成[Ag(L1)](NO3)二聚体,最后生成[Ag(L2)] n(NO3)n(H2O)聚合物。确实,我们观察到O…H贡献在Hirshfeld表面的百分比从(L1)传递到[Ag(L2)]
