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.
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. There is one shorter (2.75 Å) and two longer (2.84 Å) K(1)-O(2) bond lengths. There are a spread of K(1)-O(1) bond distances ranging from 2.85-3.05 Å. N(1) is bonded in a trigonal planar geometry to one O(2) and two equivalent O(1) atoms. The N(1)-O(2) bond length is 1.25 Å. Both N(1)-O(1) bond lengths are 1.26 Å. 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.
