Abstract

In the title compound, UO(2)(C(4)H(7)O(3))(2), 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.

摘要

在标题化合物[UO₂(C₄H₇O₃)₂]ₙ中，双氧铀(VI)单元通过2-羟基-2-甲基丙酸酯配体连接成蜂窝状结构。U原子呈七配位，具有五角双锥几何构型。2-羟基-2-甲基丙酸根离子的未配位羟基通过O—H⋯O氢键与铀酰的O原子以及相邻2-羟基-2-甲基丙酸根离子的配位羟基相互作用。
