Abstract

Five metal–organic frameworks, namely, [Mn3(H2DMPhIDC)2(HDMPhIDC)2(bpp)]n (H3DMPhIDC = 2-(3,4-dimethylphenyl)-1H-imidazole-4,5-dicarboxylic acid, bpp = 1,3-di(4-pyridyl)propane) (1), [Pb4(DMPhIDC)2(OH)2]n (2), [Cd(HDMPhIDC)(en)]n (en = ethylenediamine) (3), [Cu3(HDMPhIDC)3(Py)3]n (Py = pyridine) (4) and {[Zn2(HDMPhIDC)2(Phen)2]2·H2O}n (Phen = 1,10-phenanthroline) (5) have been hydro(solvo)thermally synthesized and structurally characterized by single-crystal X-ray diffraction, elemental and thermal analyses and IR spectra. Polymer 1 displays a 3D noninterpenetrated framework with 1D open channels. Polymer 2 exhibits a stepped (4,4,4,4,6,6)-connect 2D topology. Polymer 3 is a left-handed helix chain. Polymers 4 and 5 arrange the 3D supramolecular networks containing a 1D corrugated chain via π⋯π stacking or hydrogen bond interactions. In these MOFs, the imidazole dicarboxylate ligand shows various coordination modes and strong coordination ability. Furthermore, the solid-state luminescent properties of the polymers have also been discussed.
