The structure described by KC2N3 crystallizes in the orthorhombic Pnma space group. K(1) is bonded in a 7-coordinate geometry to two equivalent N(2), two equivalent N(3), and three equivalent N(1) atoms. There are two inequivalent C sites. In the first C site, C(1) is bonded in a linear geometry to one N(1) and one N(3) atom. In the second C site, C(2) is bonded in a linear geometry to one N(2) and one N(3) atom. There are three inequivalent N sites. In the first N site, N(1) is bonded to three equivalent K(1) and one C(1) atom to form a mixture of distorted corner and edge-sharing NK3C tetrahedra. In the second N site, N(2) is bonded in a 3-coordinate geometry to two equivalent K(1) and one C(2) atom. In the third N site, N(3) is bonded in a distorted bent 120 degrees geometry to two equivalent K(1), one C(1), and one C(2) atom. is represented by the CIF file [CIF]
