Materials Data on YbNiC2 by Materials Project
YbNiC2 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. All Yb–C bond lengths are 2.65 Å. Ni2+ is bonded in a 4-coordinate geometry to four equivalent C+2.50- atoms. There is two shorter (1.96 Å) and two longer (1.98 Å) Ni–C bond length. C+2.50- is bonded in a 7-coordinate geometry to four equivalent Yb3+, two equivalent Ni2+, and one C+2.50- atom. The C–C bond length is 1.33 Å.
