Abstract

Four complexes with supramolecular architectures, namely, MZCA·3H2O (1), [Zn(H2O)6]2+·[MZCA]2·[H2O]6 (2), [Mn(MZCA)2(H2O)4]·2H2O (3), and [Ni(MZCA)2(H2O)4]·2H2O (4) [MZCA = 3-(carboxymethyl)-2, 7-dimethyl-3H-benzo[d]imidazole-5-carboxylic acid], were synthesized and characterized by elemental analysis, IR spectroscopy, and single-crystal X-ray diffraction. Complexes 1 and 2 display a remarkable 3D network with 1D hydrophilic channels. Complexes 3 and 4 are isostructural and exhibit a 3D structure encapsulating 1D 24-membered ring microporous channels. The UV/Vis and fluorescent spectra were measured to characterize complexes 14. The thermal stability of complexes 24 were also examined.
