The material described by Na2SO5 crystallizes in the orthorhombic Cmcm space group. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded in a distorted hexagonal planar geometry to two equivalent O(1) and four equivalent O(2) atoms. In the second Na site, Na(2) is bonded in a distorted square co-planar geometry to four equivalent O(2) atoms. S(1) is bonded in a distorted square pyramidal geometry to one O(1) and four equivalent O(2) atoms. There are two 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 4-coordinate geometry to one Na(1), one Na(2), one S(1), and one O(2) atom. is represented by the CIF card [CIF]
