The structure described by K2CdN12 crystallizes in the monoclinic C2/m space group. K(1) is bonded in a 8-coordinate geometry to one N(1), two equivalent N(3), two equivalent N(4), and three equivalent N(6) atoms. Cd(1) is bonded to two equivalent N(4) and four equivalent N(1) atoms to form edge-sharing CdN6 octahedra. There are six inequivalent N sites. In the first N site, N(1) is bonded to one K(1), two equivalent Cd(1), and one N(2) atom to form a mixture of distorted edge and corner-sharing NKCd2N tetrahedra. In the second N site, N(2) is bonded in a linear geometry to one N(1) and one N(3) atom. In the third N site, N(3) is bonded in a distorted T-shaped geometry to two equivalent K(1) and one N(2) atom. In the fourth N site, N(4) is bonded in a 4-coordinate geometry to two equivalent K(1), one Cd(1), and one N(5) atom. In the fifth N site, N(5) is bonded in a linear geometry to one N(4) and one N(6) atom. In the sixth N site, N(6) is bonded in a 4-coordinate geometry to three equivalent K(1) and one N(5) atom. is represented by the CIF file [CIF]
