Materials Data on Ba3FeN3 by Materials Project
Ba3FeN3 crystallizes in the hexagonal P6_3/m space group. The structure is three-dimensional. Ba2+ is bonded to five equivalent N3- atoms to form a mixture of distorted edge and corner-sharing BaN5 trigonal bipyramids. There are a spread of Ba–N bond distances ranging from 2.84–3.18 Å. Fe3+ is bonded in a trigonal planar geometry to three equivalent N3- atoms. All Fe–N bond lengths are 1.74 Å. N3- is bonded in a distorted single-bond geometry to five equivalent Ba2+ and one Fe3+ atom.
