Hydrothermal syntheses, structures, and properties of four metal–organic coordination polymers assembled from V-shaped tetracarboxylate ligands and N-donor ancillary ligands
摘要:
A series of four metal-organic frameworks, namely, [Cu(sdpa)(0.5)(2,2'-bpy)]center dot H2O (1), [Zn-2(sdpa)(2,2'-bpy)(2)(H2O)(2)]center dot 3H(2)O (2), [Zn-2(sdpa)(4,4'-bpy)]center dot 3H(2)O (3), [Cd-2(sdpa)(4,4'-bpy)(1.5)(H2O)(2)] (4), have been hydro(solvo)thermally synthesized through the reaction of 2,3,2',3'-sulfonyldiphthalic acid (H(4)sdpa) with divalent copper, zinc and cadmium salts in the presence of ancillary nitrogen ligands (4,4'-bpy = 4,4'-bipyridine, 2,2'-bpy = 2,2'-bipyridine) and structurally characterized by elemental analysis, IR and X-ray diffraction. Both complex 1 and 2 show metal-organic chain structure, and the adjacent chains are further linked by pi center dot center dot center dot pi and C-H center dot center dot center dot pi in interactions for 1 and hydrogen bonds and pi center dot center dot center dot pi interactions for 2 to form 3D supramolecular structure. In complex 3, two Zn1 and two Zn2 atoms appear alternately and are bridged by sdpa(4-) anion ligands to form an infinite Zn-sdpa chain. Such chains are further linked together through 4,4'-bpy ligands in four orientations to form a robust 3D metal-organic network. In compound 4, a 3D Cd-sdpa metal-organic network is accomplished through sdpa(4-) anion ligands, and further stabilized by 4,4'-bpy in six orientations. Their luminescence and thermal analysis have also been investigated. (C) 2010 Elsevier Ltd. All rights reserved.
