The material structure described by Ba2MgYBiO6 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(1), two equivalent O(3), and four equivalent O(2) atoms. In the second Ba site, Ba(2) is bonded in a distorted q6 geometry to one O(3), two equivalent O(2), two equivalent O(4), and four equivalent O(1) atoms. Mg(1) is bonded in a distorted trigonal non-coplanar geometry to one O(4) and two equivalent O(1) atoms. Y(1) is bonded in a 6-coordinate geometry to one O(3), one O(4), two equivalent O(1), and two equivalent O(2) atoms. Bi(1) is bonded in a distorted octahedral geometry to one O(3), one O(4), two equivalent O(1), and two equivalent O(2) atoms. There are four inequivalent O sites. In the first O site, O(1) is bonded in a 6-coordinate geometry to one Ba(1), two equivalent Ba(2), one Mg(1), one Y(1), and one Bi(1) atom. In the second O site, O(2) is bonded in a 5-coordinate geometry to one Ba(2), two equivalent Ba(1), one Y(1), and one Bi(1) atom. In the third O site, O(3) is bonded in a 5-coordinate geometry to one Ba(2), two equivalent Ba(1), one Y(1), and one Bi(1) atom. In the fourth O site, O(4) is bonded in a 6-coordinate geometry to one Ba(1), two equivalent Ba(2), one Mg(1), one Y(1), and one Bi(1) atom. is represented by the CIF file [CIF]
