Ferric ammonium oxalate
Chemical compound
Ferric ammonium oxalate (ammonium ferrioxalate, ammonium tris(oxalato)ferrate) is the ammonium salt of the anionic trisoxalato coordination complex of iron(III). It is a precursor to iron oxides, diverse coordination polymers, and Prussian Blue.[1][2] The latter behavior is relevant to the manufacture of blueprint paper. Ferric ammonium oxalate has also been used in the synthesis of superconducting salts with bis(ethylene)dithiotetrathiafulvalene (BEDT-TTF), see Organic superconductor.[3]
