The structure described by CsMgAs(H6O5)2 crystallizes in the cubic F-43m space group. Cs(1) is bonded to twelve equivalent O(1) atoms to form distorted CsO12 cuboctahedra that share corners with twelve equivalent Cs(1)O12 cuboctahedra and faces with four equivalent Mg(1)O6 octahedra. Mg(1) is bonded to six equivalent O(1) atoms to form MgO6 octahedra that share faces with four equivalent Cs(1)O12 cuboctahedra. As(1) is bonded in a tetrahedral geometry to four equivalent O(2) atoms. H(1) is bonded in a distorted linear geometry to one O(1) and one O(2) atom. There are two inequivalent O sites. In the first O site, O(2) is bonded to one As(1) and three equivalent H(1) atoms to form corner-sharing OAsH3 tetrahedra. In the second O site, O(1) is bonded in a distorted trigonal planar geometry to two equivalent Cs(1), one Mg(1), and two equivalent H(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
