We present Mossbauer studies of the influence of excess iron atoms on the properties of ironbased superconductor Fe1.09SeO.5TeO.5. Mossbauer spectra were collected in a temperature range from liquid helium up to room temperature. The temperature dependences of hyperfine parameters was investigated. The Mossbauer spectra have shown a complex shape and could be treated with a model based on first principle density functional theory calculation results similar to that in Ref. [3].
