resumo
Two novel zinc complexes, [Zn(H-hqc)(2)(bpy)(H2O)(2)] (1) and [Zn(H-hqc)(2)(bpe)]center dot H2O (2), where H-2-hqc=2-hydroxyquinoline-4-carboxylic acid, bpy=4,4'-bipyridine and bpe=1,2-bi(4-pyridyl)ethylene, have been prepared under hydrothermal condition. Complex 1 displays a 10 rigid linear chain structure while complex 2 displays 1D flexible zig-zag chain structure. Coordination number of the central Zn ion in complex 1 is six and in complex 2 is four. The structural differences of these complexes suggest the effect of size of the bridging ligands on the construction of metal organic frameworks with the same metal ion under solvothermal conditions.
