Structural diversity of six metal–organic frameworks from a rigid bisimidazole ligand and their adsorption of organic dyes

Abstract

Six metal–organic frameworks, namely, [Cd2(odc)2(2,6-bin)2]·(CH3)2NH (1), [Cd2(tdc)2(2,6-bin)2(H2O)2] (2), [Cd2(bzdc)2(2,6-bin)2]·4DMF (3), [Cd2(hfdc)2(2,6-bin)2]·H2O (4), [Cd3(tpo)2(2,6-bin)3(H2O)4]·2DMF·2H2O (5) and [Zn3(btb)2(2,6-bin)]·8DMF (6) {2,6-bin = 2,6-bisimidazoylnaphthalene, H2odc = 4,4′-oxybisbenzoic acid, H2tdc = thiophene-2,5-dicarboxyl acid, H2bzdc = benzophenone-4,4′-dicarboxylic acid, H2hfdc = 2,2′-bis(4-carboxyphenyl)hexafluoropropane, H3tpo = tris-(4-carboxylphenyl)phosphine oxide and H3btb = 4,4′,4′′-benzene-1,3,5-triyl-tribenzoic acid} have been synthesized and structurally characterized. Compound 1 exhibits a three-fold interpenetration of 4T25 network. Compound 2 presents a five-fold interpenetration of dia network. Compound 3 displays a 2D → 2D three-fold interpenetration of sql layers. Compound 4 features a 2D → 3D parallel polycatenation of sql layers. Compound 5 exhibits an unusual 3,4,6-connected self-catenated network of 3,4,6T206 topology. Compound 6 shows a rare 3,8-connected self-catenated network of 3,8T72 topology. Their adsorption behaviors to organic dyes have been studied.
