In the title compound, [U(C(9)H(4)INO(4)S)O(2)(H(2)O)(3)].2H(2)O, the asymmetric unit contains a UO(2)(2+) ion coordinated by the N and O atoms of a 7-iodo-8-oxidoquinoline-5-sulfonate dianion (ferron anion) and three coordinated water molecules, and two uncoordinated water molecules. The UO(2)(2+) ion exhibits a seven-coordinate pentagonal bipyramidal geometry. The usual sulfonate oxygen coordination is absent but the sulfonate O atoms, along with the coordinated and lattice water molecules, play a vital role in assembling the three-dimensional structure via an extensive network of intermolecular O-H...O hydrogen bonds and pi-pi stacking interactions.
在标题化合物[U(C₉H₄INO₄S)O₂(H₂O)₃]·2H₂O中，不对称单元包含一个UO₂²⁺离子，它由7-碘-8-氧化喹啉-5-磺酸盐二阴离子（铁试剂阴离子）的N和O原子以及三个配位水分子配位，还有两个未配位水分子。UO₂²⁺离子呈现七配位的五角双锥几何构型。不存在通常的磺酸根氧配位，但磺酸根O原子与配位水分子和晶格水分子一起，通过广泛的分子间O-H...O氢键网络和π-π堆积相互作用在组装三维结构中起着至关重要的作用。
