In order to search for phonon reference for dimer-gapped superconducting Mo_3Sb_7, measurements of specific heat (C_p(T)) and electrical resistivity (ρ(T)) of Ru_3Sn_7 were performed in the temperature range 2-300 K. The phonon part of C_p(T) and ρ(T) of Ru_3Sn_7 can satisfactorily be explained describing the spectrum with one Einstein and two Debye modes. We found Θp_{E} ≈ 100 K, Θp_{D1} ≈ 185 K and Θp_{D2} ≈298 K. The magnetic specific heat of Mo_3Sb_7 exhibits a sharp maximum at T*= 50 K, below which follows a gap function. Magnetic resistivity increases as -lnT with decreasing temperature and shows maximum at T*.
