KCN3O2 crystallizes in the monoclinic P2_1/c space group. K(1) is bonded in a 9-coordinate geometry to one N(3), three equivalent N(1), two equivalent O(1), and three equivalent O(2) atoms. C(1) is bonded in a linear geometry to one N(1) and one N(3) atom. There are three inequivalent N sites. In the first N site, N(1) is bonded in a distorted single-bond geometry to three equivalent K(1) and one C(1) atom. In the second N site, N(2) is bonded in a distorted trigonal planar geometry to one N(3), one O(1), and one O(2) atom. In the third N site, N(3) is bonded in a distorted single-bond geometry to one K(1), one C(1), and one N(2) atom. There are two 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(2) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to three equivalent K(1) and one N(2) atom.
