MgPr(BiO3)2 is Pb(Zr_(1-x)Ti_x)O3-derived structured and crystallizes in the tetragonal P4/mnc space group. Mg(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form MgO6 octahedra that share corners with six equivalent Pr(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 0-44°. Pr(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form PrO6 octahedra that share corners with six equivalent Mg(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 0-44°. Bi(1) is bonded in a 4-coordinate geometry to four equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a linear geometry to one Mg(1) and one Pr(1) atom. In the second O site, O(2) is bonded in a 4-coordinate geometry to one Mg(1), one Pr(1), and two equivalent Bi(1) atoms.
