Ternary compounds SmNi_{2}Sn_{2} and SmCu_{2}Sn_{2} were investigated with the X-ray diffraction, magnetic susceptibility and electric resistivity methods, as well as using the ^{119}Sn Mossbauer effect under the applied magnetic field. Magnetic susceptibilities of these compounds show the Curie-Weiss behaviour in the temperature range from 15 K to 280 K with the enhanced values of the temperature independent term χ_{0}. Both resistivity and magnetic measurements indicate the occurrence of the magnetic ordering in SmCu_{2}Sn_{2} below T_{N} = 8 K. The Mossbauer investigations carried out at 4.2 K under an applied magnetic field of up 6 T indicate a more complex magnetic structure and a considerable anisotropy. SmNi_{2}Sn_{2} remains paramagnetic down to 5 K.
