The material structure described by CaPr(CuO3)2 is Orthorhombic Perovskite-derived structured and 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. Cu(1) is bonded to one O(1), one O(4), two equivalent O(2), and two equivalent O(3) atoms to form corner-sharing CuO6 octahedra. The corner-sharing octahedral tilt angles range from 22-26°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to one Ca(1), one Pr(1), and two equivalent Cu(1) atoms. 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 Cu(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 Cu(1) atoms. In the fourth O site, O(4) is bonded in a 4-coordinate geometry to one Ca(1), one Pr(1), and two equivalent Cu(1) atoms. is represented by the CIF card [CIF]
