Addition and redox reactivity of hydrogen sulfides (H2S/HS -) with nitroprusside: New chemistry of nitrososulfide ligands

The nitroprusside ion [Fe(CN)5NO]2- (NP) reacts with excess HS- in the pH range 8.5-12.5, in anaerobic medium ("Gmelin" reaction). The progress of the addition process of HS - into the bound NO+ ligand was monitored by stopped-flow UV/Vis/EPR and FTIR spectroscopy, mass spectrometry, and c...
