Materials Data on Sr2LiCoN2 by Materials Project
LiSr2CoN2 crystallizes in the tetragonal P4_2/mnm space group. The structure is three-dimensional. Li1+ is bonded in a linear geometry to two equivalent N3- atoms. Both Li–N bond lengths are 2.03 Å. Sr2+ is bonded to four equivalent N3- atoms to form a mixture of distorted edge and corner-sharing SrN4 tetrahedra. All Sr–N bond lengths are 2.67 Å. Co1+ is bonded in a linear geometry to two equivalent N3- atoms. Both Co–N bond lengths are 1.81 Å. N3- is bonded to one Li1+, four equivalent Sr2+, and one Co1+ atom to form a mixture of edge and corner-sharing NSr4LiCo octahedra. The corner-sharing octahedra tilt angles range from 0–61°.
