TaRu3 is Uranium Silicide-like structured and crystallizes in the hexagonal P6_3/mmc space group. Ta(1) is bonded to twelve equivalent Ru(1) atoms to form TaRu12 cuboctahedra that share corners with six equivalent Ta(1)Ru12 cuboctahedra, corners with twelve equivalent Ru(1)Ta4Ru8 cuboctahedra, edges with eighteen equivalent Ru(1)Ta4Ru8 cuboctahedra, faces with eight 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 four equivalent Ta(1)Ru12 cuboctahedra, corners with fourteen equivalent Ru(1)Ta4Ru8 cuboctahedra, edges with six equivalent Ta(1)Ru12 cuboctahedra, edges with twelve equivalent Ru(1)Ta4Ru8 cuboctahedra, faces with four equivalent Ta(1)Ru12 cuboctahedra, and faces with sixteen equivalent Ru(1)Ta4Ru8 cuboctahedra.

There are six shorter (2.71 Å) and six longer (2.78 Å) Ta(1)-Ru(1) bond lengths. Ru(1) is bonded to four equivalent Ta(1) and eight equivalent Ru(1) atoms to form distorted RuTa4Ru8 cuboctahedra that share corners with four equivalent Ta(1)Ru12 cuboctahedra, corners with fourteen equivalent Ru(1)Ta4Ru8 cuboctahedra, edges with six equivalent Ta(1)Ru12 cuboctahedra, edges with twelve equivalent Ru(1)Ta4Ru8 cuboctahedra, faces with four equivalent Ta(1)Ru12 cuboctahedra, and faces with sixteen equivalent Ru(1)Ta4Ru8 cuboctahedra. There are a spread of Ru(1)-Ru(1) bond distances ranging from 2.70-2.79 Å.
