YbTa crystallizes in the hexagonal P-6m2 space group. Yb(1) is bonded to six equivalent Yb(1) and six equivalent Ta(1) atoms to form YbYb6Ta6 cuboctahedra that share corners with eighteen equivalent Yb(1)Yb6Ta6 cuboctahedra, edges with six equivalent Yb(1)Yb6Ta6 cuboctahedra, edges with twelve equivalent Ta(1)Yb6Ta6 cuboctahedra, faces with eight equivalent Yb(1)Yb6Ta6 cuboctahedra, and faces with twelve equivalent Ta(1)Yb6Ta6 cuboctahedra. Ta(1) is bonded to six equivalent Yb(1) and six equivalent Ta(1) atoms to form TaYb6Ta6 cuboctahedra that share corners with eighteen equivalent Ta(1)Yb6Ta6 cuboctahedra, edges with six equivalent Ta(1)Yb6Ta6 cuboctahedra, edges with twelve equivalent Yb(1)Yb6Ta6 cuboctahedra, faces with eight equivalent Ta(1)Yb6Ta6 cuboctahedra, and faces with twelve equivalent Yb(1)Yb6Ta6 cuboctahedra.
