An optimized synthetic method is presented for Sm2Ru3Sn5 and investigate its physical properties and electronic structure. Sm2Ru3Sn5 is prepared by arc-melting stoichiometric ratios of the elements and is confirmed by single crystal and powder X-ray diffraction. An antiferromagnetic transition is observed at TN = 3.8 K. A modified Curie-Weiss fit to the data in the range 50–150 K yields a Curie-Weiss temperature: θCW = −36.6 K and an effective magnetic moment: μeff = 0.83 μB, in agreement with a Sm3+ oxidation state. Field-dependent magnetization up to H = 7 T at 2 K shows a maximum response of 0.06 μB, which is significantly lower than the expected Sm3+ saturation moment (0.71 μB). Resistivity measurements indicate metallic behavior, and analysis of the magnetic entropy from the heat capacity reveals a doublet ground state due to crystal electric field splitting. The electronic structure and density of states are calculated with density function theory and further supported by the local density approximation with dynamical mean-field theory. Finally, the experimental and computational results highlight localized Sm3+ moments and suggest a possible interplay between Ruddelman–Kitel–Kasuya–Yosida and Kondo interactions, positioning Sm2Ru3Sn5 as a promising material for studying topology and complex physical phenomena.
