Materials Data on BaZrN2 by Materials Project
BaZrN2 crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Ba2+ is bonded to five equivalent N3- atoms to form a mixture of edge and corner-sharing BaN5 square pyramids. There are one shorter (2.78 Å) and four longer (2.98 Å) Ba–N bond lengths. Zr4+ is bonded in a 5-coordinate geometry to five N3- atoms. There are one shorter (2.01 Å) and four longer (2.23 Å) Zr–N bond lengths. There are two inequivalent N3- sites. In the first N3- site, N3- is bonded to five equivalent Ba2+ and one Zr4+ atom to form distorted NBa5Zr octahedra that share corners with four equivalent NBa5Zr octahedra, corners with four equivalent NZr4 trigonal pyramids, and edges with eight equivalent NBa5Zr octahedra. The corner-sharing octahedral tilt angles are 7°. In the second N3- site, N3- is bonded to four equivalent Zr4+ atoms to form distorted NZr4 trigonal pyramids that share corners with four equivalent NBa5Zr octahedra, corners with four equivalent NZr4 trigonal pyramids, and edges with four equivalent NZr4 trigonal pyramids. The corner-sharing octahedral tilt angles are 71°.
