Abstract
The hydrothermal reaction of the tricarboxylate ligand 5-(carboxymethoxy)isophthalic acid (H3L) with ZnII, CdII, and SnII salts in the presence of the bisbenzoimidazole coligand 1, 3-bis(benzimidazol-2-yl)-2-oxapropane (bbop) afforded the coordination polymers, [Zn(HL)(bbop)]n (1), [Cd(HL)(bbop)]n (2), and {[H2(bbop)][Sn2L2]}n (3). The complexes were characterized by elemental analyses, IR spectroscopy, single-crystal X-ray diffraction analyses, thermogravimetric analyses, and fluorescence properties. The structures of complexes 1 and 2 are constructed by 1D chains and show strong blue luminescence emission. The structure of complex 3 is a 2D anionic dilayer, and shows a vase-like porous structure occupied by the bulky [H2(bbop)]2+ cation, which is an uncommon structural feature in transition metal coordination polymers. The three complexes are further connected by hydrogen bonds to form 3D supramolecular architectures.
