KN3O4 crystallizes in the monoclinic P2_1/c space group. K(1) is bonded in a 11-coordinate geometry to two equivalent N(2), two equivalent O(1), two equivalent O(2), two equivalent O(4), and three equivalent O(3) atoms. There are three inequivalent N sites. In the first N site, N(1) is bonded in a distorted trigonal planar geometry to one N(2), one O(3), and one O(4) atom. In the second N site, N(2) is bonded in a 2-coordinate geometry to two equivalent K(1), one N(1), and one N(3) atom. In the third N site, N(3) is bonded in a distorted trigonal planar geometry to one N(2), one O(1), and one O(2) atom. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to two equivalent K(1) and one N(3) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to two equivalent K(1) and one N(3) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to three equivalent K(1) and one N(1) atom. In the fourth O site, O(4) is bonded in a distorted single-bond geometry to two equivalent K(1) and one N(1) atom.
