摘要: Four Ag-based coordination polymers [Ag(Bim)] (1), [Ag2(NIPH)(HBim)] (2), [Ag6(4-NPTA)(Bim)4] (3) and [Ag2(3-NPTA)(bipy)0.5(H2O)] (4) (HBim = 1H-benzimidazole, bipy 4,4′-bipyridyl, H2NIPH 5-nitroisophthalic acid, H2NPTA 3-/4-nitrophthalic acid) have been synthesized by hydrothermal reaction of Ag(I) salts with N-/O-donor ligands. Single-crystal X-ray diffraction indicated that these constructed from mononuclear or polynuclear silver building blocks exhibit three typical structure features 1-D to 3-D frameworks. These compounds favour a slow release Ag+ ions leading excellent long-term antimicrobial activities, which is distinguished their different topological structures, towards both Gram-negative bacteria, Escherichia coli (E. coli) Gram-positive Staphylococcus aureus (S. aureus). In addition, show good thermal stability light under UV-vis visible light, are important characteristics for further application in antibacterial agents.
