Chromous ferrocyanide complexes have been prepared by mixing K 4 Fe(CN) 6 and CrCl 2 in the molar ratioes 1: 1, 1: 2 and 1: 4. The analysis showed the existence of K 2 CrFe(CN) 6 , Cr 2 Fe(CN) 6 and K 2 Cr 3 [Fe(CN) 6 ] 2 . The complexes are endowed with great adsorptive capacity for constituent ions and more so for ferrocyanide. A quantitative study showed that the ‘normal’ complex Cr 2 Fe(CN) 6 adsorbs one mole of Fe(CN) 6 4− and 0.3 mole of Cr ++ in aqueous medium and 0.1 M of each in presence of 10% alcohol. The complexes have got very little hydrolytic tendency.
