The material structure described by Pr(SnO3)2 crystallizes in the orthorhombic Pmn2_1 space group. Pr(1) is bonded in a 8-coordinate geometry to one O(1), one O(4), two equivalent O(2), and four equivalent O(3) atoms. Sn(1) is bonded to one O(1), one O(4), two equivalent O(2), and two equivalent O(3) atoms to form corner-sharing SnO6 octahedra. The corner-sharing octahedral tilt angles range from 15-37°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one Pr(1) and two equivalent Sn(1) atoms. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to one Pr(1) and two equivalent Sn(1) atoms. In the third O site, O(3) is bonded in a distorted rectangular see-saw-like geometry to two equivalent Pr(1) and two equivalent Sn(1) atoms. In the fourth O site, O(4) is bonded in a T-shaped geometry to one Pr(1) and two equivalent Sn(1) atoms. is represented by the CIF card [CIF]
