Materials Data on HoFeC2 by Materials Project
HoFeC2 crystallizes in the orthorhombic Amm2 space group. The structure is three-dimensional. Ho3+ is bonded in a 8-coordinate geometry to eight equivalent C3- atoms. There are four shorter (2.60 Å) and four longer (2.68 Å) Ho–C bond lengths. Fe3+ is bonded in a 4-coordinate geometry to four equivalent C3- atoms. There is two shorter (1.91 Å) and two longer (1.99 Å) Fe–C bond length. C3- is bonded in a 7-coordinate geometry to four equivalent Ho3+, two equivalent Fe3+, and one C3- atom. The C–C bond length is 1.41 Å.
