Based on an asymmetric 1-(2-carboxyethyl)-1H-1,2,4-triazole-3-carboxylic acid (H(2)ctp), six new MOFs [Cd (ctp)(H2O)](n) (1), [Cd-2(ctp)(2)(phen)](n) (2) [phen = 1,10-Phenanthroline monohydrate], [Cd-2(ctp)(2)(pbbbm)(H2O)(2)](n) (3) [pbbbm = 1,4-bis(benzimidazole-1-ylmethyl)benzene)], [Mn(ctp)(H2O)](n) (4), {[Pb-2(ctp)(2)]center dot H2O}(n) (5) and [Cu(ctp)(H2O)(2)](n) (6) have been synthesized and structurally characterized by single-crystal X-ray diffraction, elemental analysis and IR spectroscopy. 1, 4 and 5 display (4,4)-connected 3-D frameworks which all can be simplified into the Schlafli symbol of (4(2).6(3).8) with sra topology, while 2 is also a (4,4)-connected 3-D network which has the Schlafli symbol of (4(2).8(4)) with pts topology. 3 exhibits a 2-D structure with 3,4L83 topology and 6 is a 1-D chain structure. The fluorescent properties of 1- 3 and 5 have been studied in the solid state at room temperature. 5 has significantly stronger fluorescence emission than 1- 3 due to its crystal structure features. The antibacterial activities of 1-6 against four strains bacteria of Bacillus subtilis, Staphylococcus aureus, Salmonella enteritidis and Escherichia coli have been examined. The results indicated that 2 has better activity against Bacillus subtilis than 1, 3, 4 and 6 due to the effect of chelation, auxiliary ligands and the Cd(II) ion with the feature of strong toxicity.
