The compound described by Pr2Fe2Si2C crystallizes in the monoclinic C2/m space group. Pr(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 8-coordinate geometry to five equivalent Pr(1) and three equivalent Fe(1) atoms. C(1) is bonded to four equivalent Pr(1) and two equivalent Fe(1) atoms to form distorted edge-sharing CPr4Fe2 octahedra. is represented by the Crystallographic Information File (CIF) [CIF]
