Revealing H 2 S (bio)inorganic chemistry : The reaction between sodium nitroprusside ([Fe(CN) 5 NO] 2− ) and hydrogen sulfide (HS − ), known since the late 19th century, was re‐investigated by J. A. Olabe and co‐workers ( Chem. Eur. J. 2011 , 17 , 4145), where the putative new species with nitrososulfide ligands were characterized ([Fe(CN) 5 N(O)SH] 3− with λ max = 570 nm and Fe(CN) 5 N(O)S] 4− with λ max = 535 nm; p K a =10.5±0.1). In our Correspondence we provide evidence that questions the chemical character of those species and call for further, more physiologically relevant studies.
