The material structure described by TbMn2SiC crystallizes in the orthorhombic Cmcm space group. Tb(1) is bonded in a 4-coordinate geometry to three equivalent Si(1) and four equivalent C(1) atoms. Mn(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 three equivalent Tb(1) and six equivalent Mn(1) atoms. C(1) is bonded to four equivalent Tb(1) and two equivalent Mn(1) atoms to form a mixture of corner and edge-sharing CTb4Mn2 octahedra. The corner-sharing octahedral tilt angles are 20°. is represented by the CIF card [CIF]
