NaSrPrBiO6 crystallizes in the orthorhombic Pnnn space group. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded in a distorted rectangular see-saw-like geometry to four equivalent O(2) atoms. In the second Na site, Na(2) is bonded in a distorted rectangular see-saw-like geometry to four equivalent O(3) atoms. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a body-centered cubic geometry to four equivalent O(1) and four equivalent O(2) atoms. In the second Sr site, Sr(2) is bonded in a 8-coordinate geometry to four equivalent O(1) and four equivalent O(3) atoms. Pr(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form PrO6 octahedra that share corners with six equivalent Bi(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 27-40°. Bi(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form BiO6 octahedra that share corners with six equivalent Pr(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 27-40°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted see-saw-like geometry to one Sr(1), one Sr(2), one Pr(1), and one Bi(1) atom. In the second O site, O(2) is bonded to one Na(1), one Sr(1), one Pr(1), and one Bi(1) atom to form a mixture of distorted corner and edge-sharing ONaSrPrBi tetrahedra. In the third O site, O(3) is bonded to one Na(2), one Sr(2), one Pr(1), and one Bi(1) atom to form a mixture of distorted corner and edge-sharing ONaSrPrBi tetrahedra.
