This is a body centered tetragonal lattice. Ga-II atoms are in the same (001) plane with the Hf atoms when z2 + z3 = ½.

When z1 = 1/4, z2 = 5/12, and z3 = 1/12, the atoms are on the sites of the Indium (A6) lattice. If, in this case, c = 6a, the atoms are on the sites of a face-centered cubic lattice, and if c = 6 a/sqrt(2), the atoms are on the site of a body-centered cubic lattice. This lattice is placed with the face-centered cubic lattices because most known structures have c near 6a.

See these vectors in a better notation.
