Structural and magnetic properties of 1D coordination polymers constructed by isophthalate and 2,4′-bipyridine
چکیده انگلیسی
Three new complexes {[Cu(ip)(2,4′-bpy)2] · H2O}n (1), {[Co(ip)(2,4′-bpy)2] · H2O}n (2) and [Ni(ip)(2,4′-bpy)2(H2O)]n (3) were prepared in the reaction of isophthalic acid (H2ip) with different metal ions such as CuII, CoII, and NiII under hydrothermal conditions in the presence of 2,4′-bipyridine (2,4′-bpy) ligand. The metal ions are bridged by ip2− anions to form 1D ribbon with 8-membered and 16-membered ring in complexes 1 and 2, while nickel ions are bridged by ip2− anions and water molecules forming 1D ribbon with 8-membered and 20-membered ring in complex 3. It was found that antiferromagnetic interactions between metal ions can be tuned by the nature of metal center and/or the coordinated water molecule.
