Materials Data on CaMoN3 by Materials Project
Abstract
CaMoN3 crystallizes in the monoclinic P2/m space group. The structure is three-dimensional. Ca2+ is bonded to six N+2.67- atoms to form CaN6 octahedra that share corners with two equivalent CaN6 octahedra, corners with two equivalent MoN5 trigonal bipyramids, edges with two equivalent CaN6 octahedra, and edges with four equivalent MoN5 trigonal bipyramids. The corner-sharing octahedral tilt angles are 42°. There are a spread of Ca–N bond distances ranging from 2.35–2.56 Å. Mo6+ is bonded to five N+2.67- atoms to form MoN5 trigonal bipyramids that share corners with two equivalent CaN6 octahedra, corners with four equivalent MoN5 trigonal bipyramids, edges with four equivalent CaN6 octahedra, and edges with two equivalent MoN5 trigonal bipyramids. The corner-sharing octahedral tilt angles are 49°. There are a spread of Mo–N bond distances ranging from 1.94–2.24 Å. There are three inequivalent N+2.67- sites. In the first N+2.67- site, N+2.67- is bonded in a 3-coordinate geometry to two equivalent Ca2+ and one N+2.67- atom. The N–N bond length is 1.19 Å. In the second N+2.67- site, N+2.67- is bonded to two equivalent Ca2+ and three equivalent Mo6+ atoms to form NCa2Mo3 trigonal bipyramids that share corners with four equivalent NCa2Mo3 trigonal bipyramids, corners with two equivalent NCa2Mo2more »
