SrPrMnO4 is (La,Ba)CuO4-derived structured and crystallizes in the tetragonal I4mm space group. Sr(1) is bonded in a 9-coordinate geometry to one O(1), four equivalent O(2), and four equivalent O(3) atoms. Pr(1) is bonded in a 9-coordinate geometry to one O(2), four equivalent O(1), and four equivalent O(3) atoms. Mn(1) is bonded to one O(1), one O(2), and four equivalent O(3) atoms to form corner-sharing MnO6 octahedra. The corner-sharing octahedral tilt angles are 8°. There are three inequivalent O sites.
