Materials Data on Ce(C2N3)3 by Materials Project
Ce(C2N3)3 crystallizes in the orthorhombic Cmcm space group. The structure is zero-dimensional and consists of four Ce(C2N3)3 clusters. Ce3+ is bonded in a 3-coordinate geometry to three N3- atoms. There are two shorter (2.16 Å) and one longer (2.61 Å) Ce–N bond lengths. There are two inequivalent C4+ sites. In the first C4+ site, C4+ is bonded in a bent 150 degrees geometry to two N3- atoms. There is one shorter (1.61 Å) and one longer (2.21 Å) C–N bond length. In the second C4+ site, C4+ is bonded in a single-bond geometry to one N3- atom. The C–N bond length is 1.22 Å. There are four inequivalent N3- sites. In the first N3- site, N3- is bonded in a 5-coordinate geometry to one Ce3+ and four equivalent C4+ atoms. In the second N3- site, N3- is bonded in an L-shaped geometry to one C4+ and one N3- atom. The N–N bond length is 1.19 Å. In the third N3- site, N3- is bonded in a linear geometry to two equivalent N3- atoms. In the fourth N3- site, N3- is bonded in a distorted bent 150 degrees geometry to one Ce3+ and one C4+ atom.
