| 中文摘要 | Although the 2.2'-biphenyldicarboxylate ligand (2,2'-dpa) has been widely used to construct metal-organic frameworks (MOFs) with helical sub-structure. the effect of the helical arrangement of spin carriers on the magnetic properties remains rarely scarce. In this article, two unique magnetic metal-organic supramolecular frameworks with different structural features,[Cu-2(dpa)(2)(H2O)2(4,4'-dpdo)0.5](n)(1) and [Ni(H2O)4(dpa)] center dot (4,4'-dpdo)(H2O) (2) (dpdo = 4,4'-dipyridine-N,N'-dioxide), have been isolated from the direct reaction of H(2)dpa with their corresponding salts in the presence of dpdo. In complex 1, the Cu-dpa double-helical chains, which are bridged by long flexible mu(2)-dpdo ligands to give rise to a regular 6 3 covalent layer, exhibit strong antiferromagnetic coupling interactions. Whereas the 1D [Ni(dpa)(n) helical chains in complex 2 exhibit weak antiferromagnetic coupling interactions. Rich hydrogen bonds between perpendicular 1D (Ni(dpa)](n) helical chains and quasi-1D (dpdo)(n) chains result in an intricate 3D supramolecular network. (c) 2007 Elsevier B.V. All rights reserved. |
