摘要 | The self-assembly of transition metal salts with dicarboxylate ligands and second ligands afford a series of entangled coordination frameworks based on different metal clusters, namely, [Ni-2(oba)(2)(bpy)(2)(H2O)(2)]center dot(DMF)(H2O)(2) (1), [Ni-2(oba)(2)(bpy)(2)(sa)(H2O)(2)]center dot(H2O)(4) (2), [Cu-5(oba)(4)(bpy)(5)(pca)(2)(H2O)(4)]center dot(H2O)(9) (3), [Co-3(oba)(2)(bpy)(2)(dbca)(2)]center dot(H2O)(6) (4), [Co-3(oba)(2)(dbca)(2)(H2O)] (5) and [Co-3(oba)(2)(bph)(2)(SO4)]center dot(H2O)(4) (6) [oba = 4,4'-oxydibenzoic acid; bpy = 4,4'-bipyridine; dbca = [1,1'-biphenyl]-2,2'-dicarboxylic acid; sa = 2-hydroxybenzoic acid; pca = picolinic acid; bph = (1E,2E)-1,2-bis(pyridin-4-ylmethylene)hydrazine]. Their structures were determined by single-crystal X-ray diffraction analysis and further characterized by elemental analysis, IR spectra and TG analyses. The auxiliary ligands play important roles in the formation of various entangled networks. 1 shows a box-like structure and is interlocked in a parallel fashion. Compound 2 represents the first example of a 3D polycatenated framework with different size arms. 3 displays 2D -> 3D entangled polymers with polycatenated and polythreaded features based on 4,4-sql layers, which are formed by short/long alternate pillars. 4 shows an interesting framework of 2D -> 3D polythreading feature with a Co-3 cluster occupying the corner of the grid. However, 5 displays 3D polycatenation with a 1D zigzag metal chain. An unusual [Co3SO4] unit, which is linked by four bph ligands and four oba ligands, exhibiting an anionic three-dimensional (3D) framework is observed in 6. Compounds 4-6 display antiferromagnetic properties. |
