About: Ferrioxalate

An Entity of Type: chemical substance, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

Ferrioxalate or trisoxalatoferrate(III) is a trivalent anion with formula [Fe(C2O4)3]3−. It is a transition metal complex consisting of an iron atom in the +3 oxidation state and three bidentate oxalate ions C2O2−4 anions acting as ligands. The ferrioxalate anion gives a lime green color to salts, and in solution it is fluorescent. The anion is sensitive to light and higher-energy electromagnetic radiation, which causes the decomposition of one oxalate to carbon dioxide (CO2) and reduction of the iron(III) atom to iron(II). This property is exploited for actinometry.

dbo:abstract
  • Ferrioxalate or trisoxalatoferrate(III) is a trivalent anion with formula [Fe(C2O4)3]3−. It is a transition metal complex consisting of an iron atom in the +3 oxidation state and three bidentate oxalate ions C2O2−4 anions acting as ligands. The ferrioxalate anion gives a lime green color to salts, and in solution it is fluorescent. The anion is sensitive to light and higher-energy electromagnetic radiation, which causes the decomposition of one oxalate to carbon dioxide (CO2) and reduction of the iron(III) atom to iron(II). This property is exploited for actinometry. The most common and most-studied salt is potassium ferrioxalate, but the sodium, , and salts have also received some attention. (en)
  • L'anion ferrioxalate, ou tris(oxalato)ferrate(III), est un complexe de formule chimique [Fe(C2O4)3]3−. Il est formé d'anions oxalate C2O42− chélatant un cation de fer Fe3+ à l'état d'oxydation +3. Il donne une couleur vert citron à ses sels et est fluorescent en solution. Il est sensible à la lumière et aux rayonnements électromagnétiques de haute énergie, qui induisent sa décomposition en dioxyde de carbone et la réduction du fer(III) en fer(II), propriété utilisée en actinométrie. Le sel de ferrioxalate le plus couramment étudié est le ferrioxalate de potassium K3[Fe(C2O4)3], mais les sels de sodium Na+, d'ammonium NH4+ et de lithium Li+ ont également fait l'objet de recherches.
