Crystal Structure of Photosensitive Uranyl Ethoxycarboxylate Complexes

Abstract Two photosensitive uranyl complexes have been prepared and examined by a single-crystal X-ray diffraction study. Both compounds crystallize in the monoclinic system. In bis(β-ethoxypropionato)dioxouranium(VI), uranyl ions are equatorially coordinated by six carboxylate oxygen atoms, forming one-dimensional infinite chains. In bis(ethoxyacetato)dioxouranium(VI), uranyl ions are equatorially coordinated by four carboxylate and one ethoxy oxygen atoms, forming two-dimensional network of uranyl-ligand infinite chains.
