Abstract: In the title compound, [UO2(C4H7O3)2]n, the dioxouranium(VI) units are linked by 2-hydroxy-2-methylpropionate ligands into a honeycomb structure. The U atom is seven-coordinate in a pentagonal-bipyramidal geometry. The uncoordinated hydroxy groups of the 2-hydroxy-2-methylpropionate ions interact with the O atom of the uranyl and with the coordinated hydroxy group of an adjacent 2-hydroxy-2-methylpropionate ion through O-HO hydrogen bonds.
