The crystal structure described by NaGa(SO4)2 crystallizes in the monoclinic C2/m space group. Na(1) is bonded in a distorted hexagonal planar geometry to two equivalent O(1) and four equivalent O(2) atoms. Ga(1) is bonded to two equivalent O(3) and four equivalent O(2) atoms to form GaO6 octahedra that share corners with six equivalent S(1)O4 tetrahedra. S(1) is bonded to one O(1), one O(3), and two equivalent O(2) atoms to form SO4 tetrahedra that share corners with three equivalent Ga(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 40-47°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 2-coordinate geometry to one Na(1) and one S(1) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to one Na(1), one Ga(1), and one S(1) atom. In the third O site, O(3) is bonded in a bent 150 degrees geometry to one Ga(1) and one S(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
