TbMn2SiC crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Tb4+ is bonded in a 4-coordinate geometry to three equivalent Si4- and four equivalent C4- atoms. There are one shorter (2.97 Å) and two longer (2.99 Å) Tb–Si bond lengths. All Tb–C bond lengths are 2.60 Å. Mn2+ is bonded in a distorted single-bond geometry to three equivalent Si4- and one C4- atom. There are two shorter (2.39 Å) and one longer (2.42 Å) Mn–Si bond lengths. The Mn–C bond length is 1.83 Å. Si4- is bonded in a 9-coordinate geometry to three equivalent Tb4+ and six equivalent Mn2+ atoms. C4- is bonded to four equivalent Tb4+ and two equivalent Mn2+ atoms to form a mixture of edge and corner-sharing CTb4Mn2 octahedra. The corner-sharing octahedral tilt angles are 21°.
