Ba2MgPrSbO6 crystallizes in the triclinic P-1 space group. Ba(1) is bonded in a 6-coordinate geometry to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms. Mg(1) is bonded in a square co-planar geometry to two equivalent O(2) and two equivalent O(3) atoms. Pr(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form PrO6 octahedra that share corners with six equivalent Sb(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 13-37°. Sb(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form distorted SbO6 octahedra that share corners with six equivalent Pr(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 13-37°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted rectangular see-saw-like geometry to two equivalent Ba(1), one Pr(1), and one Sb(1) atom. In the second O site, O(2) is bonded to two equivalent Ba(1), one Mg(1), one Pr(1), and one Sb(1) atom to form a mixture of distorted corner and edge-sharing OBa2PrMgSb trigonal bipyramids. In the third O site, O(3) is bonded to two equivalent Ba(1), one Mg(1), one Pr(1), and one Sb(1) atom to form a mixture of distorted corner and edge-sharing OBa2PrMgSb trigonal bipyramids.
