Abstract

In the title compound, [UO(2)(C(4)H(7)O(3))(2)](n), the dioxouranium(VI) units are linked by 2-hydr-oxy-2-methyl-propionate ligands into a honeycomb structure. The U atom is seven-coordinate in a penta-gonal-bipyramidal geometry. The uncoordinated hydr-oxy groups of the 2-hydr-oxy-2-methyl-propionate ions inter-act with the O atom of the uranyl and with the coordinated hydr-oxy group of an adjacent 2-hydr-oxy-2-methyl-propionate ion through O-H⋯O hydrogen bonds.
