The compound described by Hf5ZnSb3 crystallizes in the hexagonal P6_3/mcm space group. There are two inequivalent Hf sites. In the first Hf site, Hf(1) is bonded to two equivalent Zn(1) and five equivalent Sb(1) atoms to form a mixture of distorted corner, edge, and face-sharing HfZn2Sb5 pentagonal bipyramids. In the second Hf site, Hf(2) is bonded in a 6-coordinate geometry to six equivalent Sb(1) atoms. Zn(1) is bonded to six equivalent Hf(1) atoms to form distorted face-sharing ZnHf6 octahedra. Sb(1) is bonded in a 9-coordinate geometry to four equivalent Hf(2) and five equivalent Hf(1) atoms. is represented by the CIF file [CIF]
