Synthesis, spectroscopic and structural properties of uranyl complexes based on bipyridine N-oxide ligands
Abstract
<p>By using 2,2′-bipyridine N-oxide (bipyO) and 2,2′-bipyridine N,N′-dioxide (bipyO<sub>2</sub>), three new uranyl complexes [UO<sub>2</sub>(bipyO)SO<sub>4</sub>]·H<sub>2</sub>O (1), [UO<sub>2</sub>(bipyO)(OH)(NO<sub>3</sub>)]<sub>2</sub>·H<sub>2</sub>O (2) and [UO<sub>2</sub>(bipyO<sub>2</sub>)H<sub>2</sub>O](ClO<sub>4</sub>)<sub>2</sub>·(3) were synthesized using uranyl salts including non-coordinating or weakly coordinating power of the ClO<sub>4</sub><sup>-</sup>anion and the strongly coordinating power of NO<sub>3</sub><sup>-</sup>and SO<sub>4</sub><sup>2-</sup>anions. All of the compounds were characterized by CHN microanalytical procedures, infrared and luminescence spectroscopy and by single crystal X-ray diffraction. Spectroscopic studies indicate that the bipyO is bound to the uranyl group via the nitrogen and oxygen atoms. Structural analyses revealed that overall bonding pattern is different in each case: 1 is a polymer; in 2 dimeric complex molecules are formed, whereas 3 is composed of monomers. In all of the complexes, the uranium atom is in a seven-coordinate environment. © 2010 Elsevier Ltd. All rights reserved.</p>
