Self-assembly of polyoxoselenitopalladate nanostars [Pd15(μ3-SeO3)10(μ3-O)10Na]9- and their supramolecular pairing in the solid state

An anionic Pd15-oxo-cluster [Pd15(l3-SeO3)10(l3-O)10Na]9- has been synthesized. It is the result of an unprecedented selfassembly of Pd2+ and Na+ cations, SeO3 2- and oxo anions. It has been found for the first time, that selenito groups can give rise to supramolecular interactions in the solid state with palladium atoms, through the selenium electron lone pairs
