Abstract: | In the title compound, C10H9N2+·C9H5INO4S?·2H2O, 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 viaπ–π 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. |
