ScRu3 is Uranium Silicide-like structured and crystallizes in the tetragonal I4/mmm space group. Sc(1) is bonded to four equivalent Ru(2) and eight equivalent Ru(1) atoms to form ScRu12 cuboctahedra that share corners with four equivalent Sc(1)Ru12 cuboctahedra, edges with eight equivalent Sc(1)Ru12 cuboctahedra, edges with sixteen equivalent Ru(1)Sc4Ru8 cuboctahedra, faces with four equivalent Sc(1)Ru12 cuboctahedra, and faces with eight equivalent Ru(1)Sc4Ru8 cuboctahedra. There are two inequivalent Ru sites. In the first Ru site, Ru(1) is bonded to four equivalent Sc(1), four equivalent Ru(1), and four equivalent Ru(2) atoms to form distorted RuSc4Ru8 cuboctahedra that share corners with twelve equivalent Ru(1)Sc4Ru8 cuboctahedra, edges with eight equivalent Sc(1)Ru12 cuboctahedra, edges with eight equivalent Ru(1)Sc4Ru8 cuboctahedra, faces with four equivalent Sc(1)Ru12 cuboctahedra, and faces with ten equivalent Ru(1)Sc4Ru8 cuboctahedra. In the second Ru site, Ru(2) is bonded in a distorted square co-planar geometry to four equivalent Sc(1) and eight equivalent Ru(1) atoms.
