Title: Materials Data on Fe11MoC4 by Materials Project

Abstract

MoFe5C2(Fe3C)2 crystallizes in the monoclinic Pm space group. The structure is two-dimensional and consists of one Fe3C sheet oriented in the (0, 1, 0) direction and one MoFe5C2 sheet oriented in the (0, 1, 0) direction. In the Fe3C sheet, there are four inequivalent Fe sites. In the first Fe site, Fe is bonded in a single-bond geometry to one C atom. The Fe–C bond length is 1.79 Å. In the second Fe site, Fe is bonded in a single-bond geometry to one C atom. The Fe–C bond length is 1.88 Å. In the third Fe site, Fe is bonded in a square co-planar geometry to four C atoms. There are two shorter (2.01 Å) and two longer (2.04 Å) Fe–C bond lengths. In the fourth Fe site, Fe is bonded in a square co-planar geometry to four C atoms. There are a spread of Fe–C bond distances ranging from 1.99–2.04 Å. There are two inequivalent C sites. In the first C site, C is bonded to six Fe atoms to form a mixture of corner and edge-sharing CFe6 octahedra. The corner-sharing octahedra tilt angles range from 0–1°. In the second C site, C is bonded to six Fe atomsmore » to form a mixture of corner and edge-sharing CFe6 octahedra. The corner-sharing octahedra tilt angles range from 0–1°. In the MoFe5C2 sheet, Mo is bonded in a square co-planar geometry to four C atoms. There are a spread of Mo–C bond distances ranging from 2.10–2.12 Å. There are three inequivalent Fe sites. In the first Fe site, Fe is bonded in a single-bond geometry to one C atom. The Fe–C bond length is 1.89 Å. In the second Fe site, Fe is bonded in a single-bond geometry to one C atom. The Fe–C bond length is 1.90 Å. In the third Fe site, Fe is bonded in a square co-planar geometry to four C atoms. There are a spread of Fe–C bond distances ranging from 1.92–1.95 Å. There are two inequivalent C sites. In the first C site, C is bonded to two equivalent Mo and four Fe atoms to form a mixture of corner and edge-sharing CFe4Mo2 octahedra. The corner-sharing octahedra tilt angles range from 0–1°. In the second C site, C is bonded to two equivalent Mo and four Fe atoms to form a mixture of corner and edge-sharing CFe4Mo2 octahedra. The corner-sharing octahedra tilt angles range from 0–1°.« less
