The structure described by Y2MgGe2 crystallizes in the tetragonal P4/mbm space group. Mg(1) is bonded in a square co-planar geometry to four equivalent Ge(1) atoms. Y(1) is bonded in a 6-coordinate geometry to six equivalent Ge(1) atoms. Ge(1) is bonded in a 9-coordinate geometry to two equivalent Mg(1), six equivalent Y(1), and one Ge(1) atom. is represented by the CIF file [CIF]
