K3ZnNO3Cl4 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 one O(2), two equivalent O(1), two equivalent Cl(1), two equivalent Cl(2), and two equivalent Cl(3) atoms. In the second K site, K(2) is bonded in a 9-coordinate geometry to one O(2), two equivalent O(1), one Cl(1), one Cl(3), and four equivalent Cl(2) atoms. Zn(1) is bonded in a tetrahedral geometry to one Cl(1), one Cl(3), and two equivalent Cl(2) 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 4-coordinate geometry to one K(2), two equivalent K(1), and one N(1) atom. In the second O site, O(2) is bonded in a 4-coordinate geometry to one K(2), two equivalent K(1), and one N(1) atom. There are three inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a 6-coordinate geometry to one K(2), four equivalent K(1), and one Zn(1) atom. In the second Cl site, Cl(2) is bonded to two equivalent K(1), two equivalent K(2), and one Zn(1) atom to form a mixture of distorted corner and edge-sharing ClK4Zn trigonal bipyramids. In the third Cl site, Cl(3) is bonded in a distorted single-bond geometry to one K(2), four equivalent K(1), and one Zn(1) atom.
