Materials Data on Ca2CoC(NO)2 by Materials Project
Ca2CoC(NO)2 crystallizes in the tetragonal P4/mmm space group. The structure is three-dimensional. Ca2+ is bonded in a 8-coordinate geometry to four equivalent N3- and four equivalent O2- atoms. All Ca–N bond lengths are 2.82 Å. All Ca–O bond lengths are 2.47 Å. Co2+ is bonded in a square co-planar geometry to four equivalent O2- atoms. All Co–O bond lengths are 1.83 Å. C4+ is bonded in a linear geometry to two equivalent N3- atoms. Both C–N bond lengths are 1.25 Å. N3- is bonded in a distorted single-bond geometry to four equivalent Ca2+ and one C4+ atom. O2- is bonded to four equivalent Ca2+ and two equivalent Co2+ atoms to form a mixture of distorted corner, edge, and face-sharing OCa4Co2 octahedra. The corner-sharing octahedral tilt angles are 0°.
