The material described by KPr(SnO3)4 crystallizes in the orthorhombic Amm2 space group. K(1) is bonded in a 12-coordinate geometry to two equivalent O(2), two equivalent O(3), four equivalent O(1), and four equivalent O(4) atoms. Pr(1) is bonded in a 10-coordinate geometry to two equivalent O(2), two equivalent O(3), two equivalent O(5), and four equivalent O(1) atoms. Sn(1) is bonded to one O(2), one O(3), one O(4), one O(5), and two equivalent O(1) atoms to form corner-sharing SnO6 octahedra. The corner-sharing octahedral tilt angles range from 2-27°. There are five inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to one K(1), one Pr(1), and two equivalent Sn(1) atoms. In the second O site, O(2) is bonded in a distorted square co-planar geometry to one K(1), one Pr(1), and two equivalent Sn(1) atoms. In the third O site, O(3) is bonded in a 3-coordinate geometry to one K(1), one Pr(1), and two equivalent Sn(1) atoms. In the fourth O site, O(4) is bonded in a distorted square co-planar geometry to two equivalent K(1) and two equivalent Sn(1) atoms. In the fifth O site, O(5) is bonded in a distorted T-shaped geometry to one Pr(1) and two equivalent Sn(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
