TaRu3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Ta(1) is bonded to twelve equivalent Ru(1) atoms to form TaRu12 cuboctahedra that share corners with twelve equivalent Ta(1)Ru12 cuboctahedra, edges with twenty-four equivalent Ru(1)Ta4Ru8 cuboctahedra, faces with six equivalent Ta(1)Ru12 cuboctahedra, and faces with twelve equivalent Ru(1)Ta4Ru8 cuboctahedra. Ru(1) is bonded to four equivalent Ta(1) and eight equivalent Ru(1) atoms to form distorted RuTa4Ru8 cuboctahedra that share corners with twelve equivalent Ru(1)Ta4Ru8 cuboctahedra, edges with eight equivalent Ta(1)Ru12 cuboctahedra, edges with sixteen equivalent Ru(1)Ta4Ru8 cuboctahedra, faces with four equivalent Ta(1)Ru12 cuboctahedra, and faces with fourteen equivalent Ru(1)Ta4Ru8 cuboctahedra.
