The crystal structure described by Ba2MgYSbO6 crystallizes in the orthorhombic Immm space group. Ba(1) is bonded in a 9-coordinate geometry to one Mg(1), four equivalent O(1), and four equivalent O(2) atoms. Mg(1) is bonded in a square co-planar geometry to two equivalent Ba(1) and four equivalent O(1) atoms. Y(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form YO6 octahedra that share corners with six equivalent Sb(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 0-8°. Sb(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form SbO6 octahedra that share corners with six equivalent Y(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 0-8°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 5-coordinate geometry to two equivalent Ba(1), one Mg(1), one Y(1), and one Sb(1) atom. In the second O site, O(2) is bonded in a 6-coordinate geometry to four equivalent Ba(1), one Y(1), and one Sb(1) atom. is represented by the CIF card [CIF]
