MHg Clusters With High Coordination Numbers

The recently [25] published Mg(NH3)6Hg22 is an outstanding new member of this group of amalgams. It is characterized by a coordination polyhedron of 32 Hg atoms around each cationic Mg(NH3)6 group. 

NaK29Hg48 A Complex Ternary Amalgam With Mercury Acting as a Pseudo Group 13 Element [9] 

Details of Cs3Hg2o, which is a beautiful new example of an amalgam with high coordination number polyhedra, have been published recently. It can be described simply as being built up by linked octa-capped icosahedra of mercury or as a framework structure related to the clathrate-I type [6].
