Materials Data on Sc2(CN2)3 by Materials Project
Sc2(CN2)3 crystallizes in the trigonal R-3c space group. The structure is three-dimensional. Sc3+ is bonded to six equivalent N3- atoms to form distorted edge-sharing ScN6 octahedra. There are three shorter (2.19 Å) and three longer (2.25 Å) Sc–N bond lengths. C4+ is bonded in a linear geometry to two equivalent N3- atoms. Both C–N bond lengths are 1.23 Å. N3- is bonded in a distorted trigonal planar geometry to two equivalent Sc3+ and one C4+ atom.
