Materials Data on Sr2NiN2 by Materials Project
Sr2NiN2 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are two inequivalent Sr2+ sites. In the first Sr2+ site, Sr2+ is bonded to five N3- atoms to form a mixture of edge and corner-sharing SrN5 square pyramids. There are three shorter (2.68 Å) and two longer (2.73 Å) Sr–N bond lengths. In the second Sr2+ site, Sr2+ is bonded to five N3- atoms to form a mixture of edge and corner-sharing SrN5 square pyramids. There are a spread of Sr–N bond distances ranging from 2.62–2.78 Å. Ni2+ is bonded in a linear geometry to two N3- atoms. There is one shorter (1.76 Å) and one longer (1.77 Å) Ni–N bond length. There are two inequivalent N3- sites. In the first N3- site, N3- is bonded to five Sr2+ and one Ni2+ atom to form a mixture of distorted edge and corner-sharing NSr5Ni octahedra. The corner-sharing octahedra tilt angles range from 0–4°. In the second N3- site, N3- is bonded to five Sr2+ and one Ni2+ atom to form a mixture of edge and corner-sharing NSr5Ni octahedra. The corner-sharing octahedra tilt angles range from 0–4°.
