The compound described by MgCe2Si2 crystallizes in the tetragonal P4/mbm space group. Mg(1) is bonded in a distorted square co-planar geometry to four equivalent Si(1) atoms. Ce(1) is bonded in a 6-coordinate geometry to six equivalent Si(1) atoms. Si(1) is bonded in a 9-coordinate geometry to two equivalent Mg(1), six equivalent Ce(1), and one Si(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
