The compound described by Cd3N2 is Corundum-like structured and crystallizes in the cubic Ia-3 space group. Cd(1) is bonded to one N(2) and three equivalent N(1) atoms to form a mixture of distorted edge and corner-sharing CdN4 trigonal pyramids. There are two inequivalent N sites. In the first N site, N(1) is bonded to six equivalent Cd(1) atoms to form a mixture of distorted edge and corner-sharing NCd6 octahedra. The corner-sharing octahedral tilt angles range from 53-56°. In the second N site, N(2) is bonded to six equivalent Cd(1) atoms to form a mixture of edge and corner-sharing NCd6 octahedra. The corner-sharing octahedral tilt angles are 56°. is represented by the CIF card [CIF]
