The material described by Pr2ZnBi4 crystallizes in the tetragonal P-4m2 space group. Pr(1) is bonded in a 10-coordinate geometry to two equivalent Zn(1), two equivalent Bi(1), two equivalent Bi(2), and four equivalent Bi(3) atoms. Zn(1) is bonded in a 8-coordinate geometry to four equivalent Pr(1) and four equivalent Bi(3) atoms. There are three inequivalent Bi sites. In the first Bi site, Bi(1) is bonded in a 8-coordinate geometry to four equivalent Pr(1) and four equivalent Bi(2) atoms. In the second Bi site, Bi(2) is bonded in a 8-coordinate geometry to four equivalent Pr(1) and four equivalent Bi(1) atoms. In the third Bi site, Bi(3) is bonded in a 6-coordinate geometry to four equivalent Pr(1) and two equivalent Zn(1) atoms. is represented by the CIF card [CIF]
