The compound described by MgGe2 is Magnesium tetraboride-like structured and crystallizes in the monoclinic C2/m space group. Mg(1) is bonded in a 8-coordinate geometry to three equivalent Ge(1) and five equivalent Ge(2) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 6-coordinate geometry to three equivalent Mg(1), one Ge(1), and two equivalent Ge(2) atoms. In the second Ge site, Ge(2) is bonded in a 7-coordinate geometry to five equivalent Mg(1) and two equivalent Ge(1) atoms. is represented by the CIF card [CIF]
