A dicarboxylate ligand, 5-carboxyl-1-carboxymethyl-2-oxidopyridinium (H(2)L), was utilized to form four complexes with the general formula [M(HL)(2)(H(2)O)] center dot 2H(2)O, M = Cu(II) (1), Zn(II) (2), Mn(II) (3), Cd(II) (4). The crystals were isomorphous, belonging to the monoclinic C2/c space group. They were constructed from 1D chains and further linked by hydrogen bonds into a novel binodal (6,8)-connected 3D supramolecular network with twofold self-penetration. Photoluminescence studies revealed that complexes 2-4 displayed intense structure-related fluorescent emission bands.
