Four new complexes, [Zn(TIBTC)(DMA)]·[NH2(CH3)2] (1), [Cd(TIBTC)(H2O)]·[NH2(CH3)2]·DMA (2), [Cd2(TIBTC)(2,2′-bipy)2(HCOO)] (3), and [Cd2(DIBTC)(2,2′-bipy)2(HCOO)] (4) (H3TIBTC = 2,4,6-triiodo-1,3,5-benzenetricarboxylic acid, H3DIBTC = 2,4-diiodo-1,3,5-benzenetricarboxylic acid, 2,2′-bipy = 2,2′-bipyridine, and DMA = dimethylacetamide), were successfully synthesized and characterized by elemental analysis, powder X-ray diffraction, infrared spectroscopy, ultraviolet-visible spectroscopy, and thermogravimetric analysis. Complexes 1 and 2 are three-dimensional supramolecular network structures, while complex 4 has a two-dimensional network structure. We preliminarily studied the fluorescence properties of the complexes and found that complexes 1-3 can detect thiamine hydrochloride, NACs, and Fe3+/Zn2+ with high sensitivity and selectivity.

Poly[tris(dimethylformamide)(μ3-2,4,6-triiodol-1,3,5-benzene tricarboxylic acid)-praseodymium (III)] {Pr(TIBTC)(DMF)3}n (1) (H3TIBTC = 2,4,6-triiodo-1,3,5-benzene tricarboxylic acid) was synthesized by the reaction of Pr(NO3)3·6H2O and H3TIBTC at 85°C in a pyrex vial. 1 was characterized by elemental analysis, IR, UV–vis, TGA, PXRD, and atomic force microscopy analytical means. Each of the central Pr ions and the three carboxyl groups from the same ligand constitute a SBU, which is then joined by a carboxyl group to form a building block. In order to further explore the functional properties of 1, we used this compound for adsorption experiments. It is found that 1 can effectively adsorb anionic dyes in aqueous solutions. In particular, there is a good adsorption efficiency for coomassie brilliant blue R-250. Therefore, 1 shows good prospects for selective adsorption of anionic dyes from wastewater solution.
