Materials Data on YbCoC2 by Materials Project
YbCoC2 crystallizes in the orthorhombic Amm2 space group. The structure is three-dimensional. Yb3+ is bonded in a 8-coordinate geometry to eight equivalent C+2.50- atoms. There are four shorter (2.65 Å) and four longer (2.71 Å) Yb–C bond lengths. Co2+ is bonded in a 4-coordinate geometry to four equivalent C+2.50- atoms. There is two shorter (1.89 Å) and two longer (1.99 Å) Co–C bond length. C+2.50- is bonded in a 7-coordinate geometry to four equivalent Yb3+, two equivalent Co2+, and one C+2.50- atom. The C–C bond length is 1.36 Å.
