Materials Data on Fe5C2 by Materials Project
Fe5C2 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are ten inequivalent Fe sites. In the first Fe site, Fe is bonded in a distorted bent 150 degrees geometry to two C atoms. There is one shorter (1.97 Å) and one longer (2.01 Å) Fe–C bond length. In the second Fe site, Fe is bonded in a 2-coordinate geometry to three C atoms. There are two shorter (1.96 Å) and one longer (2.25 Å) Fe–C bond lengths. In the third Fe site, Fe is bonded in a 2-coordinate geometry to three C atoms. There are a spread of Fe–C bond distances ranging from 1.95–2.29 Å. In the fourth Fe site, Fe is bonded in a bent 150 degrees geometry to two C atoms. There is one shorter (1.97 Å) and one longer (2.01 Å) Fe–C bond length. In the fifth Fe site, Fe is bonded in a bent 150 degrees geometry to two C atoms. There is one shorter (1.97 Å) and one longer (2.01 Å) Fe–C bond length. In the sixth Fe site, Fe is bonded to four C atoms to form distorted edge-sharing FeC4 tetrahedra. There are a spread of Fe–C bond distances ranging from 2.01–2.03 Å. In the seventh Fe site, Fe is bonded in a bent 150 degrees geometry to two C atoms. There is one shorter (1.97 Å) and one longer (2.01 Å) Fe–C bond length. In the eighth Fe site, Fe is bonded in a 2-coordinate geometry to three C atoms. There are a spread of Fe–C bond distances ranging from 1.95–2.25 Å. In the ninth Fe site, Fe is bonded in a 2-coordinate geometry to three C atoms. There are a spread of Fe–C bond distances ranging from 1.95–2.22 Å. In the tenth Fe site, Fe is bonded to four C atoms to form distorted edge-sharing FeC4 tetrahedra. There are a spread of Fe–C bond distances ranging from 2.01–2.05 Å. There are four inequivalent C sites. In the first C site, C is bonded in a 7-coordinate geometry to seven Fe atoms. In the second C site, C is bonded in a 7-coordinate geometry to seven Fe atoms. In the third C site, C is bonded in a 7-coordinate geometry to seven Fe atoms. In the fourth C site, C is bonded in a 6-coordinate geometry to seven Fe atoms.
