Abstract
AbstractThe trans‐dioxido uranyl frameworks named as [(UO2)(Aip)(DMA)] (1), H[(UO2)(Aib)3] (2) and rare cis‐dioxido [(UO2)Co(Suc)2(H2O)4] (3), and [(UO2)Ni(Suc)2(H2O)4] (4) have been synthesized, which based on 5‐aminoisophthalic acid (H2Aip), 3‐aminobenzoic acid (HAib), and succinic acid (H2Suc) as ligands. They were characterized by Fourier Transform Infrared spectra, UV‐vis absorption spectra, single‐crystal X‐ray diffraction, powder X‐ray diffraction and thermogravimetry analysis. It was found that uranium ion of the complex 1 is in the pentagonal bipyramidal coordination environment, while those of the complexes 2–4 are in the hexagonal bipyramidal coordination environment. Complexes 1, 3, and 4 are 3D network structures, 2 is a discrete structure. In particular, geometry of O=U=O for 1 and 2 are trans, ones for 3 and 4 are cis. The highest removal rate of methylene blue was almost to 96 % by complex 1 as an adsorbent, which illustrates that potential application on dye adsorption.
