The compound described by Sr2MgGaSbO6 crystallizes in the triclinic P-1 space group. Sr(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 an octahedral geometry to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms. Ga(1) is bonded in a square co-planar geometry to two equivalent O(1) and two equivalent O(2) atoms. Sb(1) is bonded in a square co-planar geometry to two equivalent O(2) and two equivalent O(3) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted see-saw-like geometry to two equivalent Sr(1), one Mg(1), and one Ga(1) atom. In the second O site, O(2) is bonded to two equivalent Sr(1), one Mg(1), one Ga(1), and one Sb(1) atom to form a mixture of edge and corner-sharing OSr2MgGaSb trigonal bipyramids. In the third O site, O(3) is bonded in a distorted see-saw-like geometry to two equivalent Sr(1), one Mg(1), and one Sb(1) atom. is represented by the CIF card [CIF]
