The compound described by Ba2MgSmSbO6 crystallizes in the monoclinic Cm space group. There are two inequivalent Ba sites. In the first Ba site, Ba(1) is bonded in a 3-coordinate geometry to one O(4), two equivalent O(2), and two equivalent O(3) atoms. In the second Ba site, Ba(2) is bonded in a 7-coordinate geometry to one O(1), two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms. Mg(1) is bonded in a 5-coordinate geometry to one O(4), two equivalent O(2), and two equivalent O(3) atoms. Sm(1) is bonded in a distorted trigonal bipyramidal geometry to one O(1), two equivalent O(2), and two equivalent O(3) atoms. Sb(1) is bonded in a distorted T-shaped geometry to one O(4) and two equivalent O(2) atoms. There are four inequivalent O sites. In the first O site, O(1) is bonded in a 2-coordinate geometry to one Ba(2) and one Sm(1) atom. In the second O site, O(2) is bonded in a 5-coordinate geometry to one Ba(1), one Ba(2), one Mg(1), one Sm(1), and one Sb(1) atom. In the third O site, O(3) is bonded to one Ba(1), one Ba(2), one Mg(1), and one Sm(1) atom to form distorted edge-sharing OBa2SmMg trigonal pyramids. In the fourth O site, O(4) is bonded in a 3-coordinate geometry to one Ba(1), two equivalent Ba(2), one Mg(1), and one Sb(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
