The structure described by Ho2Fe2Si2C crystallizes in the monoclinic C2/m space group. Ho(1) is bonded in a 2-coordinate geometry to five equivalent Si(1) and two equivalent C(1) atoms. Fe(1) is bonded in a distorted single-bond geometry to three equivalent Si(1) and one C(1) atom. Si(1) is bonded in a 9-coordinate geometry to five equivalent Ho(1), three equivalent Fe(1), and one Si(1) atom. C(1) is bonded to four equivalent Ho(1) and two equivalent Fe(1) atoms to form distorted edge-sharing CHo4Fe2 octahedra. is represented by the Crystallographic Information File (CIF) [CIF]
