HfZn3 is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. Hf(1) is bonded to twelve Zn(1,1,1) atoms to form a mixture of face and corner-sharing HfZn12 cuboctahedra. There are three inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a 12-coordinate geometry to four equivalent Hf(1) and eight Zn(1,1) atoms. In the second Zn site, Zn(1) is bonded in a 12-coordinate geometry to four equivalent Hf(1) and eight Zn(1,1,1) atoms. In the third Zn site, Zn(1) is bonded in a 12-coordinate geometry to four equivalent Hf(1) and eight Zn(1,1) atoms.
HfZn3 is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. Hf(1) is bonded to twelve Zn(1,1,1) atoms to form a mixture of face and corner-sharing HfZn12 cuboctahedra. There are six shorter (2.78 Å) and six longer (2.88 Å) Hf(1)-Zn(1,1,1) bond lengths. There are three inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a 12-coordinate geometry to four equivalent Hf(1) and eight Zn(1,1) atoms. There are a spread of Zn(1)-Zn(1,1) bond distances ranging from 2.69-3.02 Å. In the second Zn site, Zn(1) is bonded in a 12-coordinate geometry to four equivalent Hf(1) and eight Zn(1,1,1) atoms. There are a spread of Zn(1)-Zn(1,1) bond distances ranging from 2.69-3.02 Å. In the third Zn site, Zn(1) is bonded in a 12-coordinate geometry to four equivalent Hf(1) and eight Zn(1,1) atoms. There is one shorter (2.75 Å) and one longer (3.02 Å) Zn(1)-Zn(1) bond length.
