Materials Data on Sr3IrN3 by Materials Project
Sr3IrN3 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 distorted edge and corner-sharing SrN5 trigonal bipyramids. There are a spread of Sr–N bond distances ranging from 2.67–2.91 Å. Ir3+ is bonded in a trigonal planar geometry to three equivalent N3- atoms. All Ir–N bond lengths are 1.91 Å. N3- is bonded to five equivalent Sr2+ and one Ir3+ atom to form a mixture of distorted edge and corner-sharing NSr5Ir octahedra. The corner-sharing octahedra tilt angles range from 13–49°.
