TmRu3 is Uranium Silicide-like structured and crystallizes in the tetragonal I4/mmm space group. Tm(1) is bonded to four equivalent Ru(2) and eight equivalent Ru(1) atoms to form a mixture of edge, corner, and face-sharing TmRu12 cuboctahedra. There are two inequivalent Ru sites. In the first Ru site, Ru(1) is bonded to four equivalent Tm(1) atoms to form a mixture of distorted edge and corner-sharing RuTm4 cuboctahedra. In the second Ru site, Ru(2) is bonded in a distorted square co-planar geometry to four equivalent Tm(1) atoms.
