Title: Materials Data on Ca6Cr2HN6 by Materials Project

Abstract

Ca6Cr2N6H crystallizes in the trigonal R-3 space group. The structure is three-dimensional. Ca2+ is bonded to five equivalent N3- and one H1+ atom to form a mixture of edge and corner-sharing CaHN5 octahedra. The corner-sharing octahedra tilt angles range from 0–15°. There are a spread of Ca–N bond distances ranging from 2.48–2.54 Å. The Ca–H bond length is 2.66 Å. Cr+2.50+ is bonded in a trigonal non-coplanar geometry to three equivalent N3- atoms. All Cr–N bond lengths are 1.81 Å. N3- is bonded to five equivalent Ca2+ and one Cr+2.50+ atom to form distorted NCa5Cr octahedra that share a cornercorner with one HCa6 octahedra, corners with six equivalent NCa5Cr octahedra, edges with two equivalent HCa6 octahedra, and edges with eight equivalent NCa5Cr octahedra. The corner-sharing octahedra tilt angles range from 10–84°. H1+ is bonded to six equivalent Ca2+ atoms to form HCa6 octahedra that share corners with six equivalent NCa5Cr octahedra and edges with twelve equivalent NCa5Cr octahedra. The corner-sharing octahedral tilt angles are 11°.
