The structure described by MgCe4 crystallizes in the cubic Fd-3m space group. The structure consists of a MgCe4 framework. Mg(1) is bonded in a tetrahedral geometry to four equivalent Ce(1) atoms. Ce(1) is bonded in a 4-coordinate geometry to one Mg(1) and three equivalent Ce(1) atoms. is represented by the CIF card [CIF]
