Application of the Duality Principle to Chiral Icosahedral Metal Complexes

摘要

Symmetry lowering from I_h to T symmetry in mononuclear complexes was the subject of a recent commication by Hegetschweiler and co-workers and of a corrigendum quoting two other complexes of this type previously obtained by Prinzbach and co-workers. These complexese are made up of a central ion surrounded by twelve atoms in an idealized icosahedral I_h symmetry. Becasue of the presence of four tripodal ligands in a tetrahedral arrangement, the (idealized) symmetry group of the complex is lowered to T.
