Abstract
Mossbauer spectra of alkali tris(maleato) ferrates(III), i.e., M-3[Fe(C2H2C O4)(3)] . nH(2)O [M = Li, Na, K, Cs] at 300 K display a doublet. The Mossba uer parameters indicate these complexes to be high spin with octahedral sym metry. The isomer shift shows a decreasing trend with the increase in elect ronegativity/polarizing power of the substituent cation (Li+, Na+, K+, Cs+) . A linear correlation between isomer shift values and the (Fe-O) stretchin g frequencies has also been observed.
