Materials Data on Sr3GaN3 by Materials Project
Sr3GaN3 crystallizes in the hexagonal P6_3/m space group. The structure is three-dimensional. Sr2+ is bonded to five equivalent N3- atoms to form a mixture of corner and edge-sharing SrN5 trigonal bipyramids. There are a spread of Sr–N bond distances ranging from 2.56–2.74 Å. Ga3+ is bonded in a trigonal planar geometry to three equivalent N3- atoms. All Ga–N bond lengths are 1.93 Å. N3- is bonded to five equivalent Sr2+ and one Ga3+ atom to form a mixture of distorted corner and edge-sharing NSr5Ga octahedra. The corner-sharing octahedra tilt angles range from 12–50°.
