Abstract: In the title crystal structure, [Mg₂(C₉H₄INO₄S)₂(H₂O)₆]·4H₂O, the Mg²⁺ ion has a distorted octahedral coordination geometry, surrounded by N and O atoms of the oxine ring (bidentate chelation), one of the O atoms of a sulfonate group and three water molecules. The inversion-related ligands, water molecules and Mg²⁺ ions form a cage-like dimer. These dimers are further cross-linked by O-HO hydrogen bonds. The title compound is isomorphous with earlier reported ferron complexes of Co, Ni and Zn.
