Two uranyl complexes based on pyromellitic acid were hydrothermally synthesized, and their X‐ray single‐crystal diffraction structures were determined. Complex [UO2(Hbtec)]–(Himd)+·H2O (1) (H4btec = pyromellitic acid, imd = imidazole), is an ionic complex, which shows a typical (4, 4) topological structure in the space. A heterometallic complex, UO2Cu(btec)(phen) (2) (phen = 1,10‐phenanthroline) results from the reaction of uranyl nitrate and copper(II) bromide with pyromellitic acid. The structure of complex 2 revealed that the chains of UO7 and CuO3N2 units were connected to each other through the carboxyl groups and U=O–Cu interactions to create a two‐dimensional framework.
Two uranyl complexes, UO 2 ( p-C 7 H 4 O 2 Br) 2 (H 2 O) and UO 2 (m-C 7 H 4 O 2 Br) 2 , are synthesized by hydrothermal method and their structures determined by single-crystal X-ray diffraction.has a chair configuration with two UO 2þ 2 cations. UO 2 (m-C 7 H 4 O 2 Br) 2 : R ¼ 0.0333, monoclinic, space group P2(1)/c, with a ¼ 5.1084(7) Å , b ¼ 17.642(3) Å , c ¼ 9.0716(13) Å , a ¼ 90 , ¼ 94.063(2) , ¼ 90(2) , Z ¼ 2, forms a 1D chain with the ligand (m-bromobenzoic acid) taking the bridging mode.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
