The material described by NaIO4 crystallizes in the triclinic P1 space group. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded in a distorted body-centered cubic geometry to one O(1), one O(2), one O(3), one O(4), one O(5), one O(6), one O(7), and one O(8) atom. In the second Na site, Na(2) is bonded in a distorted body-centered cubic geometry to one O(1), one O(2), one O(3), one O(4), one O(5), one O(6), one O(7), and one O(8) atom. There are eight inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal non-coplanar geometry to one Na(1), one Na(2), and one I(1) atom. In the second O site, O(2) is bonded in a trigonal planar geometry to one Na(1), one Na(2), and one I(1) atom. In the third O site, O(3) is bonded in a trigonal planar geometry to one Na(1), one Na(2), and one I(2) atom. In the fourth O site, O(4) is bonded in a trigonal planar geometry to one Na(1), one Na(2), and one I(2) atom. In the fifth O site, O(5) is bonded in a distorted trigonal non-coplanar geometry to one Na(1), one Na(2), and one I(1) atom. In the sixth O site, O(6) is bonded in a distorted trigonal non-coplanar geometry to one Na(1), one Na(2), and one I(2) atom. In the seventh O site, O(7) is bonded in a trigonal planar geometry to one Na(1), one Na(2), and one I(1) atom. In the eighth O site, O(8) is bonded in a distorted trigonal non-coplanar geometry to one Na(1), one Na(2), and one I(2) atom. There are two inequivalent I sites. In the first I site, I(1) is bonded in a distorted trigonal pyramidal geometry to one O(1), one O(2), one O(5), and one O(7) atom. In the second I site, I(2) is bonded in a distorted see-saw-like geometry to one O(3), one O(4), one O(6), and one O(8) atom. is represented by the CIF card [CIF]
