NaIO3 crystallizes in the orthorhombic Cmmm space group. Na(1) is bonded in a 4-coordinate geometry to two equivalent 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 square co-planar geometry to two equivalent Na(1) and two equivalent I(1) atoms. In the second O site, O(2) is bonded in a linear geometry to two equivalent Na(1) atoms. I(1) is bonded in a linear geometry to two equivalent O(1) atoms.
NaIO3 crystallizes in the orthorhombic Cmmm space group. Na(1) is bonded in a 4-coordinate geometry to two equivalent O(1) and four equivalent O(2) atoms. Both Na(1)-O(1) bond lengths are 3.00 Å. All Na(1)-O(2) bond lengths are 2.27 Å. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted square co-planar geometry to two equivalent Na(1) and two equivalent I(1) atoms. Both O(1)-I(1) bond lengths are 1.98 Å. In the second O site, O(2) is bonded in a linear geometry to two equivalent Na(1) atoms. I(1) is bonded in a linear geometry to two equivalent O(1) atoms.
