Materials Data on Ca(VN)2 by Materials Project
Ca(VN)2 crystallizes in the tetragonal P-4m2 space group. The structure is two-dimensional and consists of one Ca(VN)2 sheet oriented in the (0, 0, 1) direction. Ca2+ is bonded in a 4-coordinate geometry to four equivalent N3- atoms. All Ca–N bond lengths are 2.32 Å. V2+ is bonded in a bent 120 degrees geometry to two equivalent N3- atoms. Both V–N bond lengths are 1.85 Å. N3- is bonded to two equivalent Ca2+ and two equivalent V2+ atoms to form corner-sharing NCa2V2 tetrahedra.
