Materials Data on MgGe2 by Materials Project
MgGe2 is Magnesium tetraboride-like structured and crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. Mg is bonded in a 8-coordinate geometry to eight Ge atoms. There are a spread of Mg–Ge bond distances ranging from 2.89–3.16 Å. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 6-coordinate geometry to three equivalent Mg and three Ge atoms. There are one shorter (2.55 Å) and two longer (2.70 Å) Ge–Ge bond lengths. In the second Ge site, Ge is bonded in a 7-coordinate geometry to five equivalent Mg and two equivalent Ge atoms.
