The compound described by TbB2 is hexagonal omega structure structured and crystallizes in the hexagonal P6/mmm space group. Tb(1) is bonded to twelve equivalent B(1) atoms to form a mixture of face and edge-sharing TbB12 cuboctahedra. B(1) is bonded in a 9-coordinate geometry to six equivalent Tb(1) and three equivalent B(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
