Ammonium heptanitrosyltrithiotetraferrate monohydrate

L. L. Martin, G. D. Fallon and B. Wu

Abstract: The title compound, (NH₄)[Fe₄S₃(NO)₇]·H₂O, contains an Fe₄S₃ partial cubane core in which the apical iron is coordinated by one nitrosyl group and three S atoms above the plane of three Fe atoms. These three Fe atoms are in turn each coordinated by two S atoms and two nitrosyl groups. The axial O atoms hydrogen bond with the ammonium cation, creating a `tight' ion-pair, consistent with the solubility of the salt in diethyl ether.
