TEWARI¹, Brij B et al. Critical reviews on stability and photosensitizer potential of metal hexacyanoferrate (II) complexes: A possible prebiotic mineral. Rev. Bol. Quim [online]. 2016, vol.33, n.1, pp.07-19. ISSN 0250-5460.

Bismuth, cadmium, cobalt, manganese, nickel, lead, antimony and zirconium hexacyanoferrate (II) complexes or metal ferrocyanides were synthesized and characterized by elemental and spectral studies. Stability of metal hexacyanoferrate (II) complexes were recorded in heat, light (UV, VIS), different concentrations of various acids (HCl, H₂SO₄, HNO₃), different concentration of various bases (NaOH, KOH, NH₄OH), sea and tap water.The photosensitizing activity of metal hexacyanoferrate (II) complexes were tested by using potassium iodide and starch solution. Nickel, antimony and zirconium ferrocyanides were found to be possible photosensitizer during the course of chemical evolution on primitive Earth.

Palabras clave : Metal hexacyanoferrate (II) complexes; Synthesis; Stability; Oxidizer; photosensitizer.
