Title: Materials Data on Sm2Fe2Si2C by Materials Project

Abstract

Sm2Fe2Si2C crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. Sm3+ is bonded in a 2-coordinate geometry to five equivalent Si4- and two equivalent C4- atoms. There are a spread of Sm–Si bond distances ranging from 3.02–3.13 Å. Both Sm–C bond lengths are 2.63 Å. Fe3+ is bonded in a distorted single-bond geometry to three equivalent Si4- and one C4- atom. There are two shorter (2.30 Å) and one longer (2.31 Å) Fe–Si bond lengths. The Fe–C bond length is 1.79 Å. Si4- is bonded in a 8-coordinate geometry to five equivalent Sm3+ and three equivalent Fe3+ atoms. C4- is bonded to four equivalent Sm3+ and two equivalent Fe3+ atoms to form distorted edge-sharing CSm4Fe2 octahedra.
