PrZn(BiO3)2 crystallizes in the tetragonal P4/mnc space group. Pr(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form PrO6 octahedra that share corners with six equivalent Zn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 0-40°. Zn(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form ZnO6 octahedra that share corners with six equivalent Pr(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 0-40°. Bi(1) is bonded in a distorted rectangular see-saw-like geometry to four equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a linear geometry to one Pr(1) and one Zn(1) atom. In the second O site, O(2) is bonded to one Pr(1), one Zn(1), and two equivalent Bi(1) atoms to form a mixture of distorted corner and edge-sharing OPrZnBi2 tetrahedra.
