The crystal structure described by NaNO3 is Calcite-like structured and crystallizes in the trigonal R32 space group. Na(1) is bonded to six equivalent O(1) atoms to form distorted corner-sharing NaO6 pentagonal pyramids. N(1) is bonded in a trigonal planar geometry to three equivalent O(1) atoms. O(1) is bonded in a trigonal planar geometry to two equivalent Na(1) and one N(1) atom. is represented by the CIF file [CIF]
