The compound described by Ba2MgPrSbO6 crystallizes in the triclinic P1 space group. There are two inequivalent Ba sites. In the first Ba site, Ba(1) is bonded in a 6-coordinate geometry to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(6) atom. In the second Ba site, Ba(2) is bonded to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(6) atom to form distorted BaO6 octahedra that share corners with three equivalent Pr(1)O6 octahedra and  a faceface with one Pr(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 62-63°. Mg(1) is bonded in a trigonal planar geometry to one O(4), one O(5), and one O(6) atom. Pr(1) is bonded to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(6) atom to form PrO6 octahedra that share corners with three equivalent Ba(2)O6 octahedra and  a faceface with one Ba(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 62-63°. Sb(1) is bonded in a 3-coordinate geometry to one O(1), one O(2), and one O(3) atom. There are six inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to one Ba(1), one Ba(2), one Pr(1), and one Sb(1) atom.
