Abstract: The crystal structures of the proton-transfer compounds of 8-quinolinol (oxine) with the aromatic sulfonic acids 2-aminobenzenesulfonic acid (orthanilic acid) and 8-hydroxy-7-iodoquinoline-5-sulfonic acid (ferron) have been determined. In both 8-hydroxyquinolinium 2-aminobenzenesulfonate, C9H8NO+·C6H6NO3S-, (I), and 8-hydroxyquinolinium 8-hydroxy-7-iodoquinoline-5-sulfonate sesquihydrate, C9H8NO+·C9H5INO4S-·1.5H2O, (II), extensive hydrogen-bonding interactions, together with significant cation-cation [in (I)] and cation-anion [in (II)] - stacking associations, give rise to layered polymer structures.
Formula: C9H8NO+·C6H6NO3S- and C9H8NO+·C9H5INO4S-·1.5H2O
