【Abstract】 K3[Fe(C2H5P2O7)2]·4,5H2O, and K3[Fe(C2H6P2O7)2(OH)2]·3H2O have, been prepared in. solid state and characterized by chemical analysis, Mossbauer spectra, infrared spectra, gravimetric: and differential thermal analysis and conductivity measurement.The two compounds are both high spin complexes. From quadru-pole splitting, the symmetry around Fe atom has been shown by Mossbauer parameters of these complexes as . compared with the values of Fe(Ⅲ)-complexes, The, changes of isomer shifts are dependent on the strength of covalent bond between Fe (Ⅲ) and the ligands.The results of IR spectra and other measurements have also been discussed briefly. A probable stfuctural formula is given for each complex.更多还原
