Distribution of Fe ions in SrV 6-xFe xO 11 with 0 ≤ x ≤ 1.5 has been stuided by means of 57Fe Mossbauer spectroscopy and neutron powder diffraction. Rietveld analysis of the powder diffraction profiles revealed that Fe ions are not located on the octahedral site of V(1). This is consistent with the results taken by the Mossbauer spectroscopy at room temperature and 350 K. It is found that the larger δ of the Mossbauer subspectrum originates from Fe ions occupied at the V(3) sites, and the V(3) site occupancy of the Fe ions increases up to 60% as reducing x. It is also found that the valences of Fe ions at the V(2) and V(3) sites are considered to be 3+.
