The Mössbauer spectra of Fe 57 nuclei of 1 at% iron impurity atoms are investigated in some compounds of A 2 B 4 C 2 5type. The isomeric shift and the quadrupole splittings have been determined in the temperature range from −200 to +200 °C. It follows from the comparison with EPR data that in all cases the impurity atoms of Fe have the electron configuration 3d 6‐x 4s J (0 < x , y < 1) and substitute the elements of the I1 group. It has been found that the Mossbauer parameters depend cssentially on the nature of the anion and some cations. An assumption is necessary to compare data on the degree of bond ionicity in the compounds, using Mössbauer parameters.
