The compound described by NaSO4 crystallizes in the triclinic P-1 space group. Na(1) is bonded to two equivalent O(1), two equivalent O(3), and two equivalent O(4) atoms to form distorted NaO6 pentagonal pyramids that share corners with six equivalent S(1)O4 tetrahedra and edges with three equivalent Na(1)O6 pentagonal pyramids. S(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form SO4 tetrahedra that share corners with six equivalent Na(1)O6 pentagonal pyramids. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to two equivalent Na(1) and one S(1) atom. In the second O site, O(2) is bonded in a distorted water-like geometry to one S(1) and one O(2) atom. In the third O site, O(3) is bonded in a 3-coordinate geometry to two equivalent Na(1) and one S(1) atom. In the fourth O site, O(4) is bonded in a 3-coordinate geometry to two equivalent Na(1) and one S(1) atom. is represented by the CIF card [CIF]
