Materials Data on CeNdC4 by Materials Project
NdCeC4 crystallizes in the tetragonal P4/mmm space group. The structure is three-dimensional. Nd3+ is bonded in a distorted q4 geometry to ten C+1.50- atoms. There are two shorter (2.55 Å) and eight longer (2.77 Å) Nd–C bond lengths. Ce3+ is bonded in a distorted q4 geometry to ten C+1.50- atoms. There are two shorter (2.55 Å) and eight longer (2.77 Å) Ce–C bond lengths. There are two inequivalent C+1.50- sites. In the first C+1.50- site, C+1.50- is bonded in a 6-coordinate geometry to four equivalent Nd3+, one Ce3+, and one C+1.50- atom. The C–C bond length is 1.30 Å. In the second C+1.50- site, C+1.50- is bonded in a 6-coordinate geometry to one Nd3+, four equivalent Ce3+, and one C+1.50- atom. The C–C bond length is 1.30 Å.
