The structure described by MgSbAsO5 crystallizes in the orthorhombic P2_12_12_1 space group. Mg(1) is bonded in a 5-coordinate geometry to one O(2), one O(3), one O(4), and two equivalent O(5) atoms. Sb(1) is bonded in a 5-coordinate geometry to one O(3), one O(4), one O(5), and two equivalent O(1) atoms. As(1) is bonded in a tetrahedral geometry to one O(1), one O(2), one O(3), and one O(4) atom. There are five inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to two equivalent Sb(1) and one As(1) atom. In the second O site, O(2) is bonded in a bent 150 degrees geometry to one Mg(1) and one As(1) atom. In the third O site, O(3) is bonded in a 3-coordinate geometry to one Mg(1), one Sb(1), and one As(1) atom. In the fourth O site, O(4) is bonded in a 3-coordinate geometry to one Mg(1), one Sb(1), and one As(1) atom. In the fifth O site, O(5) is bonded in a distorted trigonal planar geometry to two equivalent Mg(1) and one Sb(1) atom. is represented by the CIF file [CIF]
