MgYb4Ge4 is Magnesium tetraboride-derived structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Mg is bonded in a distorted T-shaped geometry to three Ge atoms. There are a spread of Mg–Ge bond distances ranging from 2.77–2.90 Å. There are two inequivalent Yb sites. In the first Yb site, Yb is bonded in a 6-coordinate geometry to six Ge atoms. There are a spread of Yb–Ge bond distances ranging from 2.95–3.08 Å. In the second Yb site, Yb is bonded in a 7-coordinate geometry to seven Ge atoms. There are a spread of Yb–Ge bond distances ranging from 3.05–3.50 Å. There are three inequivalent Ge sites. In the first Ge site, Ge is bonded in a 8-coordinate geometry to one Mg, six Yb, and one Ge atom. The Ge–Ge bond length is 2.54 Å. In the second Ge site, Ge is bonded in a 5-coordinate geometry to seven Yb and one Ge atom. The Ge–Ge bond length is 2.50 Å. In the third Ge site, Ge is bonded in a 9-coordinate geometry to two equivalent Mg, six Yb, and one Ge atom.
