The structure described by NaClO3 crystallizes in the monoclinic P2_1/c space group. Na(1) is bonded in a 6-coordinate geometry to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to two equivalent Na(1) and one O(2) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to two equivalent Na(1) and one O(1) atom. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to two equivalent Na(1) and one Cl(1) atom. Cl(1) is bonded in a single-bond geometry to one O(3) atom. is represented by the CIF file [CIF]
