In the title compound, C(10)H(9)N(2)(+).C(9)H(5)INO(4)S(-).2H(2)O, the 4,4'-bipyridine molecule is protonated at one of the pyridine N atoms. These moieties self-assemble into a supramolecular chain along the a axis through N-H.N hydrogen bonds. The quinolinol OH group acts as a donor with respect to a sulfonate O atom [O-H.O(sulfonate)] and acts as an acceptor with respect to a C-H group of ferron [C-H.O(hydroxy)], forming a supramolecular chain along the b axis. These two types of supramolecular chains (one type made up of bipyridine motifs and the other made up of sulfoxine motifs) interact via pi-pi stacking, generating a three-dimensional framework. These chains are further crosslinked by C-H.O hydrogen bonds and O-H.O hydrogen bonds involving water molecules.
在标题化合物C(10)H(9)N(2)(+)·C(9)H(5)INO(4)S(-)·2H(2)O中，4,4'-联吡啶分子在其中一个吡啶N原子处质子化。这些部分通过N-H…N氢键沿着a轴自组装成超分子链。喹啉醇OH基团相对于磺酸根O原子[O-H…O(磺酸根)]作为供体，相对于邻二氮菲的C-H基团[C-H…O(羟基)]作为受体，沿着b轴形成超分子链。这两种类型的超分子链（一种由联吡啶基序组成，另一种由亚磺基水杨酸基序组成）通过π-π堆积相互作用，生成三维框架。这些链通过涉及水分子的C-H…O氢键和O-H…O氢键进一步交联。
