Single crystals of Na[(UO2)(i-C3H7COO)3]·0.7H2O (I), Cs[(UO2)(i-C3H7COO)3] (II) and (NH4)[(UO2)(i-C4H9COO)3] (III) were obtained via isothermal evaporation and their structures were solved using X-ray diffraction techniques. Even though the ligands are branched, bulky and spatial, many carbon and hydrogen atoms are still disordered in these crystal structures at low temperature. A new type of Na coordination is observed for the first time for this family of compounds, proposing high sensitivity of compound I to humidity. Depolymerization of the metal–oxygen frameworks for the new compounds is compared with the known ones. Coordination sequences of sodium/cesium and uranyl complexes with aliphatic monocarboxylate ions are calculated to show different crystal-chemical function of crystallographically independent atoms. As there are analogous compounds to the title ones with straight-chain ligands, such groups of similar compounds with single varying parameters are very advantageous for establishing correlations between composition and crystal structure.

异丁酸根和异戊酸根阴离子的铀酰配合物的晶体结构†
Na [（UO 2）（iC 3 H 7 COO）3 ]·0.7H 2 O（I），Cs [（UO 2）（iC 3 H 7 COO）3 ]（II）和（NH 4）的单晶[（UO 2）（iC 4 H 9 COO）3 ]（III）通过等温蒸发及其结构是使用X射线衍射技术解决的。即使配体是分支的，庞大的和空间的，在低温下这些晶体结构中仍然有许多碳和氢原子无序。该化合物家族首次观察到一种新型的Na配位，表明化合物I具有高敏感性湿度。将新化合物的金属-氧骨架的解聚与已知的进行比较。计算钠/铯和铀酰配合物与脂肪族单羧酸根离子的配位序列，以显示晶体学独立原子的不同晶体化学功能。由于存在与具有直链配体的标题化合物相似的化合物，因此具有单个可变参数的此类相似化合物基团对于建立组成与晶体结构之间的相关性非常有利。
