  The structure and magnetic properties of a 3D pillared-layer polymer and two helical chains constructed from flexible ligands

  摘要：

  Three novel coordination polymers of Coll and Cull with flexible ligands, namely [Co(oba)(dpa)](n) (1), [Cu(oba)(dpa)](n) (2) and [Cu(oba)(bpy)(1/2)](n) (3) [H(2)oba = 4,4'-oxybis(benzoic acid), dpa = 2,2'-dipyridylamine, bpy = 4,4'-bipyridine] were synthesized by hydrothermal reactions and characterized by single-crystal X-ray diffraction, thermogravimetric analyses, elemental analysis and IR spectroscopy. X-ray diffraction analysis reveals that complexes I and 2 are isostructural. In complexes I and 2, the Coll and Cull ions are linked by flexible oba ligands to form I D helical chain. These chains are further assembled into 3D supramolecular edifice via aromatic pi-pi stacking interactions and intermolecular hydrogen bonding. The Cull ions in complex 3 are linked by the carboxylate groups oba. to form an eight-membered ring chains, the connectivity between the corner-shared eight-membered ring chains are further bridged by the bent oba ligands to produce 2D helical layer containing the right-handed helical chains. Furthermore, the adjacent helical layers are connected by bpy pillars to form a novel 3D framework with an unprecedented topology of (3(15).4(20).5(8).6(2)). The magnetic properties of complexes 1-3 have also been investigated. (C) 2008 Elsevier B.V. All rights reserved.
