摘要 A dicarboxylate ligand,5-carboxyl-1-carboxymethyl-2-oxidopyridinium (H2L),was utilized to form four complexes with the general formula [M(HL)2(H2O)]·2H2O,M = CuII (1),ZnII (2),MnII (3),CdII (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.
