Three interesting metal-organic frameworks, [(Cd-2(Hpidc)(pdc)](n)(1), {[(Cd-2(Hpidc)(2)(H2O)]center dot H2O}(n) (2), {[(Cd-2(Hpidc)(2)(H2O)]center dot 2H(2)O}(n)(3) (H(3)pidc = pyridine-2-yl-1H-imidazole-4,5-dicarboxylic acid, H(2)pdc = 2,6-pyridine dicarboxylic acid) have been synthesized under hydrothermal by controlling the temperature and varying with the second organic ligands. Compounds 1 and 2 possess 3D frameworks with a new topological network with 2-nodal (6,6)-connected net and 2-nodal (5, 6)-connected net respectively. Notably, Compound 3 exhibit a 1-D interesting double Zigzag chain. The thermogravimetric and fluorescence properties of 1-3 were also explored.
