The compound described by NaSrPrSbO6 crystallizes in the orthorhombic Pnnn space group. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded in a 4-coordinate geometry to four equivalent O(1) atoms. In the second Na site, Na(2) is bonded in a square co-planar geometry to four equivalent O(2) atoms. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 8-coordinate geometry to four equivalent O(2) and four equivalent O(3) atoms. In the second Sr site, Sr(2) is bonded in a distorted body-centered cubic 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 Sb(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 25-26°. Sb(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form SbO6 octahedra that share corners with six equivalent Pr(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 25-26°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to one Na(1), one Sr(2), one Pr(1), and one Sb(1) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to one Na(2), one Sr(1), one Pr(1), and one Sb(1) atom. In the third O site, O(3) is bonded in a 3-coordinate geometry to one Sr(1), one Sr(2), one Pr(1), and one Sb(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
