MgTb4Ge4 is Magnesium tetraboride-derived structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Mg is bonded in a 5-coordinate geometry to five Ge atoms. There are a spread of Mg–Ge bond distances ranging from 2.77–3.17 Å. There are two inequivalent Tb sites. In the first Tb site, Tb is bonded in a 6-coordinate geometry to six Ge atoms. There are a spread of Tb–Ge bond distances ranging from 2.87–3.07 Å. In the second Tb site, Tb is bonded in a 7-coordinate geometry to seven Ge atoms. There are a spread of Tb–Ge bond distances ranging from 3.00–3.36 Å. There are three inequivalent Ge sites. In the first Ge site, Ge is bonded in a 9-coordinate geometry to two equivalent Mg, six Tb, and one Ge atom. The Ge–Ge bond length is 2.60 Å. In the second Ge site, Ge is bonded in a 8-coordinate geometry to one Mg, six Tb, and one Ge atom. In the third Ge site, Ge is bonded in a 9-coordinate geometry to one Mg, seven Tb, and one Ge atom. The Ge–Ge bond length is 2.72 Å.
