Four new complexes based on 1,4-naphthalenedicarboxylic acid (1,4-H2NDC) and four bis-pyridyl-bis-amide ligands with various spacers (3-bpye = N,N'-bis(3-pyridinecarboxamide)-1,2-ethane; 3-bpfp = bis(3-pyridylformyl) piperazine; 3-bpcd = N,N'-bis(pyridin-3-yl) cyclohexane-1,4-dicarboxamide; and 3-bpcb = N,N'-bis(3-pyridinecarboxamide)-1,4-benzene), namely [Cu-2(1,4-NDC) (2)(3-bpye)(H2O)] (1), [Cu(1,4-NDC)(3-bpfp)(0.5)] (2), [Cu-3(1,4-NDC)(3)(3-bpcd) 3]center dot 2H(2)O (3), and [Cu(1,4-NDC)(3-bpcb)] (4), have been hydrothermally synthesized. Complex 1 is a 3D coordination network and represents an 8-connected {4(20).6(8)} topology. Complex 2 shows a 2-fold interpenetrating 3D architecture with a 6-connected {4(12).6(3)} topology. Complexes 3 and 4 possess similar 2D sql layers with the {4(4).6(2)} topology, but the coordination modes of 1,4-NDC ligands and the conformations of the two bis-pyridyl-bis-amide ligands are different. The adjacent layers for 3 and 4 are further linked by hydrogen bonding interactions to form 3D supramolecular networks. The successful assemblies of complexes 1-4 imply that by using the different bis-pyridyl-bis-amide ligands with diverse spacers can produce diverse metal-organic networks. Furthermore, the fluorescence and photocatalytic properties of complexes 1-4 have been investigated.
