Materials Data on Cr3N2 by Materials Project
Cr3N2 is Corundum structured and crystallizes in the trigonal R-3c space group. The structure is three-dimensional. Cr2+ is bonded to four equivalent N3- atoms to form a mixture of distorted corner and edge-sharing CrN4 trigonal pyramids. There is two shorter (1.93 Å) and two longer (2.01 Å) Cr–N bond length. N3- is bonded to six equivalent Cr2+ atoms to form a mixture of corner, edge, and face-sharing NCr6 octahedra. The corner-sharing octahedra tilt angles range from 46–51°.
