Materials Data on SmCoC2 by Materials Project

SmCoC2 crystallizes in the orthorhombic Amm2 space group. The structure is three-dimensional. Sm3+ is bonded in a 8-coordinate geometry to eight equivalent C+2.50- atoms. All Sm–C bond lengths are 2.70 Å. Co2+ is bonded in a 4-coordinate geometry to four equivalent C+2.50- atoms. There is two shorter (1.95 Å) and two longer (1.99 Å) Co–C bond length. C+2.50- is bonded in a 7-coordinate geometry to four equivalent Sm3+, two equivalent Co2+, and one C+2.50- atom. The C–C bond length is 1.38 Å.

Materials Data on SmCoC2 by Materials Project

SmCoC2 crystallizes in the monoclinic Cc space group. The structure is three-dimensional. Sm3+ is bonded in a 8-coordinate geometry to eight C+2.50- atoms. There are a spread of Sm–C bond distances ranging from 2.68–2.74 Å. Co2+ is bonded in a 4-coordinate geometry to four C+2.50- atoms. There are a spread of Co–C bond distances ranging from 1.92–1.99 Å. There are two inequivalent C+2.50- sites. In the first C+2.50- site, C+2.50- is bonded in a 7-coordinate geometry to four equivalent Sm3+, two equivalent Co2+, and one C+2.50- atom. The C–C bond length is 1.38 Å. In the second C+2.50- site, C+2.50- is bonded in a 7-coordinate geometry to four equivalent Sm3+, two equivalent Co2+, and one C+2.50- atom.
