Magnetization measurements on the Heusler alloy Co2ScSn show that the system undergoes a transition from a paramagnetic state to a possible helimagnetic state at Tc=238 K, and exhibits spin-glass behavior below 100 K. 119Sn Mössbauer spectra of Co2ScSn are found to be influenced significantly by heat treatment. Single-dip spectra are observed above Tc as expected from the cubic symmetry at the Sn sites. The transferred hyperfine field at the Sn nuclei appears below Tc, increases with decreasing temperature, and has a value of 38 kOe at 4.2 K. The temperature dependence of the hyperfine field at the Sn nuclei shows a small break at 100 K which correlates with the onset of the spin-glass transition.
