We report the results of scalar and fully relativistic electronic structure calculations for nonsuperconducting Th₇Ru₃, using the full-potential linearized-muffin-thin-orbital and full-potential linearized augmented-plane wave methods. The obtained data, including electronic band structures, density of states, Fermi surfaces and electron localization function, reveal the presence of anisotropic spin-orbit coupling but its strength, exposed by splitting energies of the order of 10-40 meV, is much weaker as compared to those of Th₇Fe₃ or Th₇Co₃ superconductors. Moreover, the lack of Van Hove singularity near the Fermi level underscores a key point of the non-occurrence of superconductivity in the studied compound.
