Abstract
A new U(VI) compound with m-hydroxybenzoic acid, HIm[(UO2)(C7H5O3)3]·2H2O, was prepared. Its structure was determined by X-ray diffraction analysis and confirmed by the visible and IR spectra. The coordination number of the U atom is 8, with the hydroxyl O atom not involved in coordination with the metal ion. The main structural constituents of the compound are [(UO2)(C7H5O3)3]− anions formed by the sixcoordinate uranyl ion and three hydroxybenzoate ions acting as bidentate ligands. The imidazolium cations participate in hydrogen bonding, linking the adjacent [(UO2)(C7H5O3)3]− anions. The compound contains water molecules of crystallization, also participating in H bonding.
