The material described by Tb2Fe2Si2C crystallizes in the monoclinic C2/m space group. Tb(1) is bonded in a 1-coordinate geometry to five equivalent Si(1) and one C(1) atom. 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 11-coordinate geometry to five equivalent Tb(1), three equivalent Fe(1), one Si(1), and two equivalent C(1) atoms. C(1) is bonded in a distorted square co-planar geometry to two equivalent Tb(1), two equivalent Fe(1), and four equivalent Si(1) atoms. is represented by the CIF card [CIF]
