Cr3N2 is Corundum-like structured and crystallizes in the orthorhombic Pbcn space group. There are two inequivalent Cr sites. In the first Cr site, Cr(1) is bonded to four equivalent N(1) atoms to form a mixture of distorted corner and edge-sharing CrN4 trigonal pyramids. In the second Cr site, Cr(2) is bonded to four equivalent N(1) atoms to form a mixture of distorted corner and edge-sharing CrN4 trigonal pyramids. N(1) is bonded to two equivalent Cr(2) and four equivalent Cr(1) atoms to form a mixture of face, corner, and edge-sharing NCr6 octahedra. The corner-sharing octahedral tilt angles range from 49-71°.
Cr3N2 is Corundum-like structured and crystallizes in the orthorhombic Pbcn space group. There are two inequivalent Cr sites. In the first Cr site, Cr(1) is bonded to four equivalent N(1) atoms to form a mixture of distorted corner and edge-sharing CrN4 trigonal pyramids. There are a spread of Cr(1)-N(1) bond distances ranging from 1.94-2.14 Å. In the second Cr site, Cr(2) is bonded to four equivalent N(1) atoms to form a mixture of distorted corner and edge-sharing CrN4 trigonal pyramids. There are two shorter (1.94 Å) and two longer (2.02 Å) Cr(2)-N(1) bond lengths. N(1) is bonded to two equivalent Cr(2) and four equivalent Cr(1) atoms to form a mixture of face, corner, and edge-sharing NCr6 octahedra. The corner-sharing octahedral tilt angles range from 49-71°.
