Materials Data on Ba2CuC(NO)2 by Materials Project
Ba2CuC(NO)2 crystallizes in the tetragonal P4/mmm space group. The structure is three-dimensional. Ba2+ is bonded in a 8-coordinate geometry to four equivalent N3- and four equivalent O2- atoms. All Ba–N bond lengths are 3.02 Å. All Ba–O bond lengths are 2.75 Å. Cu2+ is bonded in a square co-planar geometry to four equivalent O2- atoms. All Cu–O bond lengths are 1.98 Å. C4+ is bonded in a linear geometry to two equivalent N3- atoms. Both C–N bond lengths are 1.24 Å. N3- is bonded in a distorted single-bond geometry to four equivalent Ba2+ and one C4+ atom. O2- is bonded to four equivalent Ba2+ and two equivalent Cu2+ atoms to form a mixture of distorted corner, edge, and face-sharing OBa4Cu2 octahedra. The corner-sharing octahedral tilt angles are 0°.
