The material structure described by Zr5ZnPb3 crystallizes in the hexagonal P6_3/mcm space group. There are two inequivalent Zr sites. In the first Zr site, Zr(1) is bonded in a 6-coordinate geometry to six equivalent Pb(1) atoms. In the second Zr site, Zr(2) is bonded to two equivalent Zn(1) and five equivalent Pb(1) atoms to form a mixture of distorted corner, face, and edge-sharing ZrZn2Pb5 pentagonal bipyramids. Zn(1) is bonded to six equivalent Zr(2) atoms to form distorted face-sharing ZnZr6 octahedra. Pb(1) is bonded in a 9-coordinate geometry to four equivalent Zr(1) and five equivalent Zr(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
