Three Co(III)-Fe(II) complexes based on hexacyanoferrates: Syntheses, spectroscopic and structural characterizations

Original language description

Red or orange crystals of [Co(NH3)6]2Cl2[Fe(CN)6].4H2O (1), [Co(en)3]2Cl2[Fe(CN)6].2H2O (2) and [Co(en)3]4[Fe(CN)6]3.21.6H2O (3) were isolated from the aqueous systems Co3+-LN-[Fe(CN)6]4- (LN = NH3, en = 1,2-diaminoethane). In all isolated samples the combination of Mossbauer (d values were from the range -0.07 to -0.08 mm/s) and IR spectra (-(C-N) stretching vibrations in the range 2015?2047 cm-1) confirms the presence of low spin Fe(II) in [Fe(CN)6]4- anions. X-ray structure analyses corroborate the ionic character of all studied compounds. These contain diamagnetic [Co(NH3)6]3+ (1) or [Co(en)3]3+ (2 and 3) complex cations and diamagnetic [Fe(CN)6]4- complex anions. In compounds 1 and 2 chloride anions are present, too. All three compounds contain water of crystallization, in compound 3 as many as 21.6 molecules per formula unit.
