TbFe2 crystallizes in the monoclinic C2/m space group. Tb(1) is bonded in a distorted square co-planar geometry to one Fe(1), one Fe(3), and two equivalent Fe(2) atoms. There are three inequivalent Fe sites. In the first Fe site, Fe(1) is bonded in a distorted linear geometry to two equivalent Tb(1) atoms. In the second Fe site, Fe(2) is bonded in a distorted linear geometry to two equivalent Tb(1) atoms. In the third Fe site, Fe(3) is bonded in a distorted linear geometry to two equivalent Tb(1) atoms.
