About: Percobaltate

An Entity of Type: Chemical114806838, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

Percobaltates are chemical compounds where the oxidation state of cobalt is +5. This is the highest established oxidation state of cobalt. The simplest of these are bi-metallic Group 1 oxides such as sodium percobaltate (Na3CoO4); which may be produced by the reaction of cobalt(II,III) oxide and sodium oxide, using oxygen as the oxidant: 4 Co3O4 + 18 Na2O + 7 O2 → 12 Na3CoO4 A number of organometallic Co(V) complexes have also been reported.

  • Percobaltates are chemical compounds where the oxidation state of cobalt is +5. This is the highest established oxidation state of cobalt. The simplest of these are bi-metallic Group 1 oxides such as sodium percobaltate (Na3CoO4); which may be produced by the reaction of cobalt(II,III) oxide and sodium oxide, using oxygen as the oxidant: 4 Co3O4 + 18 Na2O + 7 O2 → 12 Na3CoO4 The potassium salt can be synthesized similarly; its magnetic moment has indicated the existence of cobalt(V). No crystallographic analysis has been reported for either material. Percobaltates can be stabilized by use of oxides or fluorides. A number of organometallic Co(V) complexes have also been reported.
