Te-125 and Fe-57 Mossbauer spectroscopy are used to assess the tellurium sublattice and iron clustering in the pseudo two-dimensional structure of Fe-57-enriched TaFe1.25Te3. The Te-125 spectrum reveals two quadrupole signals in 1:2 intensity ratio ascribable to two sets of unequivalent tellurium atoms in a highly distorted electronic environment. The basic features of the Fe-57 Mossbauer spectra at 77 and 5 K were accounted for by a Markov chain treatment of short-range ordering (SRO) of iron atoms, while a model based on random distribution fails to describe the complex hyperfine structure of the spectra.
