Single crystals of the MgZn2Ce alloy (magnesium dizinc cerium) were synthesized by a two-step method which couples the thermal treatment of pressed pellets of the pure elements with subsequent arc melting. The compound crystallizes in a Heusler-type (MnCu2Al) structure in the space group Fm m, with one Zn site (site symmetry 3m), one Ce and one...

Icosa-cerium nona-deca-magnesium henocta-conta-zinc, Ce20Mg19Zn81, synthesized by fritting of the pure elements with subsequent arc melting, crystallizes with an unusually large cubic unit cell [space group F 3m, a = 21.1979 (8) Å] and represents a new structure type among the technologically important family of ternary rare earth-transition...
