- Abstract
The coordination polymers [Cd2(bbmb)2(L1)(HL1)0.5(H2O)] n ( 1), [Cd2(bbmb)2(L2)2(H2O) ·(H2O)] n ( 2), and [Ni(bbmb)2(L3)] n ( 3), were synthesized by the hydrothermal reaction of 4,4′-bis(benzimidazol-1-ylmethyl)biphenyl (bbmb) with CdII/NiII ions in the presence of three flexible aliphatic acids [tricarballylic acid (H3L1), succinate (H2L2), and adipate (H2L3)]. Complexes 1- 3 were structurally characterized by elemental analysis, IR spectroscopy and single-crystal and X-ray powder diffraction analyses. Complex 1 presents a 3D 3-nodal (3,4,4)-connected net with 3, 4, 4T78 topology, 2 exhibits a 3D network with 66- dia topology, whereas 3 is a chain structure and further extended by hydrogen bonding interactions to form a 2D supramolecular network. Structural diversity of these complexes indicates that these frameworks could be tuned by the conformation of bbmb ligand and the different coordination modes of the aliphatic carboxylate co-ligands. The thermal and fluorescence properties, the catalytic activities of complexes 1- 3 in a Fenton-like process were investigated.
