The material described by CsMgAs(H3O2)2 crystallizes in the cubic F-43m space group. Cs(1) is bonded to six equivalent H(1) and four equivalent O(1) atoms to form distorted CsH6O4 tetrahedra that share corners with six equivalent Mg(1)H6 octahedra and corners with four equivalent As(1)O4 tetrahedra. The corner-sharing octahedra are not tilted. Mg(1) is bonded to six equivalent H(1) atoms to form MgH6 octahedra that share corners with six equivalent Cs(1)H6O4 tetrahedra. As(1) is bonded to four equivalent O(1) atoms to form AsO4 tetrahedra that share corners with four equivalent Cs(1)H6O4 tetrahedra. H(1) is bonded in a single-bond geometry to one Cs(1) and one Mg(1) atom. O(1) is bonded in a distorted linear geometry to one Cs(1) and one As(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
