The structure described by MgCe2 crystallizes in the monoclinic C2/c space group. Mg(1) is bonded to two equivalent Mg(1) and ten equivalent Ce(1) atoms to form a mixture of edge, corner, and face-sharing MgCe10Mg2 cuboctahedra. Ce(1) is bonded in a 12-coordinate geometry to five equivalent Mg(1) and seven equivalent Ce(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
