Abstract:

The present work describes the synthesis, full characterization and architectural diversity of six new bioactive silver-organic networks, namely the coordination polymers [Ag(bpa)(2)(CF3SO3)(H2O)(n) (1), {[Ag-2(PPh3)(2)(bpa)(2)](CF3SO3)}(n) (2), [Ag(bpe)(CF3SO3)](n) (3), [Ag(bpe)(CF3SO3)(CH3CN)](n) (4), {[Ag(PPh3) (mu-bpe)](1.5)(BF4)}(n) (5) and [Ag(bpp)(CF3SO3)(CH3CN)(2)](n) (6), which are generated via a mixed-ligand strategy using 1,2-bis(4-pyridyl)ethane (bpa), 1,2-bis(4-pyridyl)ethene (bpe) or 1,3-bis(4-pyridyl)propane (bpp) as the main building block and triphenylphosphine (PPh3) as an ancillary ligand source. Complexes 1-6 were well characterized by IR, H-1 and P-31 NMR spectroscopy, elemental analysis, fluorescence, THz spectroscopy and single-crystal X-ray crystallography. The complexes 1, 2 and 4-6 have a topological network structure. The type and coordination modes of the bipyridine derivatives and the choice of solvent play a key role in defining the dimensionality as well as the structural and topological features of the resulting networks. Analysis of structures revealed that complex 1 possesses a (5(4), 6(2)) topological network structure connected through the bridging ligand bpa. Complex 2 has a dinuclear structure and displays a topologically promising architecture connected through hydrogen bonds between the C-H groups of aromatic ring and anions. Complexes 3 and 4 possess different 1D infinite chains which are linked by the bridging ligand bpe, and complex 4 can be simplified as having a three-dimensional mesh topology. Complex 5 has a (9(3), 3(3)) topological network structure connected through the bridging ligand bpe. Like complex 4, complex 6 possesses 1D infinite chains through the bridging ligand bpp, which are linked by hydrogen bonds to form a 3D topological network. Complexes 2 and 4 are generated from CH2Cl2/CH3OH (5:5) and CH3CN respectively, while the other complexes are obtained from CH3CN/H2O (5:5). In addition, complexes 1-6 exhibit interesting fluorescence in the solid state at room temperature. (C) 2015 Elsevier Ltd. All rights reserved.
