High symmetry gadolinium(III) polyhedra

Body: 

In a recent article, creation of hollow nanospheres Gd20, Gd32, Gd50 and Gd60 is described using the approach to assemble fragments containing different polygons. While structural analysis revealed the symmetries of the respective nanospheres, magnetic studies show in theory and experiment that these polyhedra show antiferromagnetic interaction which can be attributed to classical spins at the Gd sites. Magnetic measurements can even be used as "fingerprints" to identify the polyhedra.
