BaMgPrMn2O6 crystallizes in the orthorhombic Pmmm space group. Ba(1) is bonded in a 4-coordinate geometry to four equivalent O(3) atoms. Mg(1) is bonded in a square co-planar geometry to two equivalent O(1) and two equivalent O(2) atoms. Pr(1) is bonded in a distorted square co-planar geometry to four equivalent O(3) atoms. Mn(1) is bonded in a distorted square co-planar geometry to one O(1), one O(4), two equivalent O(2), and two equivalent O(3) atoms. There are four inequivalent O sites. In the first O site, O(1) is bonded in a square co-planar geometry to two equivalent Mg(1) and two equivalent Mn(1) atoms. In the second O site, O(2) is bonded in a T-shaped geometry to one Mg(1) and two equivalent Mn(1) atoms.
