The compound described by CaPr(SnO3)2 crystallizes in the orthorhombic Pmn2_1 space group. Ca(1) is bonded in a 8-coordinate geometry to one O(1), one O(4), two equivalent O(3), and four equivalent O(2) atoms. 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 34-39°. There are four inequivalent O sites. In the first O site, O(1) is bonded to one Ca(1), one Pr(1), and two equivalent Sn(1) atoms to form distorted corner-sharing OCaPrSn2 trigonal pyramids. In the second O site, O(2) is bonded in a 5-coordinate geometry to two equivalent Ca(1), one Pr(1), and two equivalent Sn(1) atoms. In the third O site, O(3) is bonded in a 5-coordinate geometry to one Ca(1), two equivalent Pr(1), and two equivalent Sn(1) atoms. In the fourth O site, O(4) is bonded to one Ca(1), one Pr(1), and two equivalent Sn(1) atoms to form distorted corner-sharing OCaPrSn2 tetrahedra. is represented by the CIF card [CIF]
