A new flexible triazine-based polycarboxylate metal-organic framework, {[Zn-4(TTHA)(4,4'-bipy)(2)(OH)(2)(H2O)] center dot H2O} n (1), H(6)TTHA =1,3,5-triazine-2,4,6-triamine hexaacetic acid, has been synthesised under hydrothermal conditions and structurally characterised by X-ray diffraction, infrared spectroscopy, elemental analysis, and X-ray single-crystal diffraction. Structural studies indicate that 1 exhibits a 3D network with a 4,6-connected topology, formed by the interconnection of tetranuclear units and the ligands. The fluorescence emission properties of 1 and the free ligands were investigated in the solid state at room temperature. Moreover, the fluorescence lifetime (t) and quantum yield (Ff) were obtained to further characterise the fluorescence properties. In addition, the water vapour adsorption of 1 was first studied for H(6)TTHA based complexes, which shows a general water adsorption capacity.
