Tb(FeB)2 crystallizes in the tetragonal I4/mmm space group. Tb(1) is bonded in a distorted body-centered cubic geometry to eight equivalent B(1) atoms. Fe(1) is bonded to four equivalent B(1) atoms to form a mixture of edge and corner-sharing FeB4 tetrahedra. B(1) is bonded in a 8-coordinate geometry to four equivalent Tb(1) and four equivalent Fe(1) atoms.
