The material described by K2NO3Cl crystallizes in the orthorhombic Pnma space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 9-coordinate geometry to three equivalent N(1), two equivalent O(1), and four equivalent O(2) atoms. In the second K site, K(2) is bonded in a 10-coordinate geometry to one N(1), three equivalent O(1), and six equivalent O(2) atoms. N(1) is bonded in a 5-coordinate geometry to one K(2), three equivalent K(1), and one Cl(1) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 6-coordinate geometry to two equivalent K(1), three equivalent K(2), and one Cl(1) atom. In the second O site, O(2) is bonded in a 6-coordinate geometry to two equivalent K(1), three equivalent K(2), and one Cl(1) atom. Cl(1) is bonded in a tetrahedral geometry to one N(1), one O(1), and two equivalent O(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
