This talk will describe the syntheses and structuresof clusters with different kinds of functional groups in the outer part of theligand shell. Therefore two different approaches are available. On the one handpara-substituted phenyl selenolatocompounds are used yielding clusters with high fluorescence, [Cu12Se3(Se�C6H4�SMe)6(PPh3)6],or intermolecular coordination via additional sulfur functions, [Cu93Se42(Se�C6H4�SMe)9(PPh3)18]2.On the other hand functionalized bidentate phosphanes can be used to synthesizenew gold selenide clusters. The figure shows the structure and ESI-TOF massspectrum of the dication [Au10Se4{(Ph2P)2N�(CH2)4�pyren}4]2+carrying four pyren ligands which could act as antennas or linkers to graphite surfacesor carbon nanotubes.
