Materials Data on Cr3N4 by Materials Project
Abstract
Cr3N4 is Corundum-like structured and crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional. there are three inequivalent Cr4+ sites. In the first Cr4+ site, Cr4+ is bonded to six N3- atoms to form a mixture of corner, edge, and face-sharing CrN6 octahedra. The corner-sharing octahedra tilt angles range from 43–49°. There are a spread of Cr–N bond distances ranging from 1.90–2.04 Å. In the second Cr4+ site, Cr4+ is bonded to six N3- atoms to form a mixture of corner, edge, and face-sharing CrN6 octahedra. The corner-sharing octahedra tilt angles range from 43–49°. There are a spread of Cr–N bond distances ranging from 1.91–2.04 Å. In the third Cr4+ site, Cr4+ is bonded to six N3- atoms to form a mixture of corner, edge, and face-sharing CrN6 octahedra. The corner-sharing octahedra tilt angles range from 43–49°. There are a spread of Cr–N bond distances ranging from 1.90–2.04 Å. There are four inequivalent N3- sites. In the first N3- site, N3- is bonded to four Cr4+ atoms to form NCr4 trigonal pyramids that share corners with two equivalent NCr6 pentagonal pyramids, corners with eight NCr4 trigonal pyramids, edges with three equivalent NCr6 pentagonal pyramids, and edges with twomore »
