Abstract Eight complexes of Cu(II), Co(II), Zn(II) and Ag(I) with rarely studied ligands, N,N-diisopropyl/butylpicolinamide ( L1 / L2 ), and N,N-diisopropyl/butylisonicotinamide ( L3 / L4 ), have been synthesized and characterized spectroscopically, and their molecular and crystal structures have been reported. Diverse coordination modes of these positional isomers have been discovered, discussed and
摘要Cu(II),Co(II),Zn(II)和Ag(I)的八种配合物,其配体,N,N-二异丙基/丁基吡啶甲酸酰胺(L1 / L2)和N,N-二异丙基/丁基异烟酰胺( L3 / L4),已经合成并进行了光谱表征,并且已经报道了它们的分子和晶体结构。鉴于它们各自的收敛和发散性质,已经发现,讨论了这些位置异构体的多样配位模式,并与有限的现有文献进行了比较。由于大量弱C–H⋯O / X和其他分子间相互作用,所有配合物均显示稳定和扩展的1D,2D或3D配位/ H键网络。此外,已经评估了配体以及金属配合物的抗微生物活性,并证明它们是有效的抗微生物剂。
