Three new transition metal coordination polymers [Cu(3-bpcb)(0.5)(5-AIP)] a <...2H(2)O (1), [Cd(3-bpc b)(0.5)(5-AIP)(H2O)] a <...H O-2 (2) and [Cd(3-bpsa)(0.5)(5-AIP)(H2O)] a <...2H(2)O (3) have been hydrothermally synthesized by self-assembly of 5-aminoisophthalic acid (5-H(2)AIP), semi-rigid or flexible bis-pyridyl-bis-amide ligands [3-bpcb = N N (')-bis(3-pyridinecarboxamide)-1,4-benzene, 3-bpsa = N,N (')-bis(3-pyridyl)succinamide], and copper chloride or cadmium nitrate. X-ray diffraction analysis reveals that compounds 1 and 2 possess similar 2 D double-layered structures with (3,4)-connected (6(3))(6(5)a <...8) topology, while compound 3 displays a 2 D layer with {6(2).10}{6} topology. The adjacent layers of 1-3 are finally extended into 3 D supramolecular frameworks by hydrogen bonding interactions. The bis-pyridyl-bis-amide ligands with different flexibilities play an important role in the construction of final topological structures for the title compounds. Further, the electrochemical behavior of the compound 1 and the fluorescent and photocatalytic properties of compounds 1-3 have been investigated.
