CaPr(AgO3)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. Ag(1) is bonded to one O(1), one O(4), two equivalent O(2), and two equivalent O(3) atoms to form corner-sharing AgO6 octahedra. The corner-sharing octahedral tilt angles range from 33-40°. 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 Ag(1) atoms to form distorted corner-sharing OCaPrAg2 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 Ag(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 Ag(1) atoms. In the fourth O site, O(4) is bonded to one Ca(1), one Pr(1), and two equivalent Ag(1) atoms to form distorted corner-sharing OCaPrAg2 trigonal pyramids.
