The compound described by MgGe5 crystallizes in the hexagonal P-62m space group. Mg(1) is bonded to six equivalent Ge(1) and six equivalent Ge(2) atoms to form a mixture of face and edge-sharing MgGe12 cuboctahedra. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a distorted trigonal planar geometry to three equivalent Mg(1) atoms. In the second Ge site, Ge(2) is bonded in a distorted water-like geometry to two equivalent Mg(1) atoms. is represented by the CIF card [CIF]
