Abstract

Mössbauer spectra of alkali tris(malonato) ferrates(III) i.e. M3[Fe(C3H2O4)3].4H2O(M=Li, Na, K, NH4) at 298±2K display a single broad absorption band due to spin lattice relaxation effect. The isomer shift values indicate these complexes to be high spin with octahedral symmetry. The isomer shift shows a decreasing trend with the increase in electronegativity/polarizing power of the substituent cation (Li+, Na+, K+, NH4 +). A linear correlation between isomer shift values and the (Fe-O) stretching freguencies has also been observed.
