The crystal structure of 8-hydroxy-7-iodoquinoline-5-sulfonic acid-urea-water, C9H6INO4S烈4N2O爲O, shows the zwitterionic (quinoline-sulfonate group) ferron molecule lying in a crystallographic mirror plane which related two of the sulfonate O atoms. Both the urea and the water molecule lie across the same plane and are inter-associated with the ferron molecules both within and between the planes by extensive hydrogen bonding, involving most available donor and acceptor sites on all three molecules. This includes a cyclic R22(8) sulfonate-urea association. The result is a three-dimensional layered structure.The crystal structure of 8-hydroxy-7-iodoquinoline-5-sulfonic acid-urea-water, C9H6INO4S烈4N2O爲O, shows the zwitterionic (quinoline-sulfonate group) ferron molecule lying in a crystallographic mirror plane which related two of the sulfonate O atoms.
