Hf3Ta is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Hf(1) is bonded to eight equivalent Hf(1) and four equivalent Ta(1) atoms to form HfHf8Ta4 cuboctahedra that share corners with twelve equivalent Hf(1)Hf8Ta4 cuboctahedra, edges with eight equivalent Ta(1)Hf12 cuboctahedra, edges with sixteen equivalent Hf(1)Hf8Ta4 cuboctahedra, faces with four equivalent Ta(1)Hf12 cuboctahedra, and faces with fourteen equivalent Hf(1)Hf8Ta4 cuboctahedra. Ta(1) is bonded to twelve equivalent Hf(1) atoms to form TaHf12 cuboctahedra that share corners with twelve equivalent Ta(1)Hf12 cuboctahedra, edges with twenty-four equivalent Hf(1)Hf8Ta4 cuboctahedra, faces with six equivalent Ta(1)Hf12 cuboctahedra, and faces with twelve equivalent Hf(1)Hf8Ta4 cuboctahedra.
