The compound described by KNO3 crystallizes in the orthorhombic Pnma space group. K(1) is bonded in a 11-coordinate geometry to three equivalent O(2) and eight equivalent O(1) atoms. N(1) is bonded in a trigonal planar geometry to one O(2) and two equivalent O(1) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to four equivalent K(1) and one N(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to three equivalent K(1) and one N(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
