Three new silver coordination polymers, namely, {Ag3(bpy)6[PW12O40]} (1), {Ag5(H2biim)2(Hbiim-NO2)2[PW12O40]} (2), {Ag7(pytz)4[PW12O40]} (3) (bpy=2,2′-bipyridine, H2biim=2,2′-biimidazole, pytz=4-(1H-tetrazol-5-yl)pyridine), have been synthesized under hydrothermal condition. Compound1shows a 3D supramolecular framework based on 0D moieties. Compound2exhibits an attractive 2D biologic screw axis. Compound3displays a 3D structure, which consists of Ag(I)···π interactions, π···π stacking and weak Ag···Ag interactions. It is noteworthy that nitration happens to compound2during the hydrothermal condition, which is quite rare. Through contrasting the antibacterial activities of gram negative and gram positive bacteria, we find compounds1–3have better antibacterial property in gram negative bacteria than gram positive bacteria. In addition, compounds1–3also exhibit efficiency of photocatalytic decomposition of organic dyes. Those compounds may be used as potential multifunctional materials in wastewater treatment, because they not only can kill bacteria but also degrade organic pollutants.
