MgPr2PtO6 is Orthorhombic Perovskite-derived structured and crystallizes in the monoclinic P2_1/c space group. Mg(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form MgO6 octahedra that share corners with six equivalent Pt(1)O6 octahedra. The corner-sharing octahedral tilt angles are 31°. Pr(1) is bonded in a 8-coordinate geometry to two equivalent O(1), three equivalent O(2), and three equivalent O(3) atoms. Pt(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form PtO6 octahedra that share corners with six equivalent Mg(1)O6 octahedra. The corner-sharing octahedral tilt angles are 31°. There are three inequivalent O sites. In the first O site, O(1) is bonded to one Mg(1), two equivalent Pr(1), and one Pt(1) atom to form distorted corner-sharing OPr2MgPt tetrahedra. In the second O site, O(2) is bonded in a 5-coordinate geometry to one Mg(1), three equivalent Pr(1), and one Pt(1) atom. In the third O site, O(3) is bonded in a 5-coordinate geometry to one Mg(1), three equivalent Pr(1), and one Pt(1) atom.
