The crystal structure described by KSrPrSbO6 crystallizes in the orthorhombic Pnnn space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 8-coordinate geometry to four equivalent O(1) and four equivalent O(2) atoms. In the second K site, K(2) is bonded in a 12-coordinate geometry to four equivalent O(1), four equivalent O(2), and four equivalent O(3) atoms. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 12-coordinate geometry to four equivalent O(1), four equivalent O(2), and four equivalent O(3) atoms. In the second Sr site, Sr(2) is bonded to four equivalent O(1), four equivalent O(2), and four equivalent O(3) atoms to form SrO12 cuboctahedra that share faces with four equivalent Pr(1)O6 octahedra and faces with four equivalent Sb(1)O6 octahedra. 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 and faces with two equivalent Sr(2)O12 cuboctahedra. The corner-sharing octahedral tilt angles range from 12-19°. 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 and faces with two equivalent Sr(2)O12 cuboctahedra. The corner-sharing octahedral tilt angles range from 12-19°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 2-coordinate geometry to one K(1), one K(2), one Sr(1), one Sr(2), one Pr(1), and one Sb(1) atom. In the second O site, O(2) is bonded in a 2-coordinate geometry to one K(1), one K(2), one Sr(1), one Sr(2), one Pr(1), and one Sb(1) atom. In the third O site, O(3) is bonded in a 5-coordinate geometry to one K(2), one Sr(1), one Sr(2), one Pr(1), and one Sb(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
