Coinage metal clusters with ethynyl ligands


Coinage metal clusters bearing an alkynyl group show a plethora of structural diversity, which is decisively determined by the alkynyl ligands and expanded by weak metal∙∙∙metal bonds. We were able to make dinuclear phosphine-gold(I) complexes easily accessible starting from carba-closo-dodecaboranylethynyl ligands. With sterically undemanding phosphine ligands, these complexes dimerize due to intermolecular aurophilic interactions to form tetranuclear gold(I) clusters, which are present both in the solid state and in solution. The aim of this project is to investigate the coordination of selected boranylethynyl ligands to coinage metal(I) fragments.
