Abstract

Homoleptic Coinage Metal Compounds of Group(IV)heteroborates. -The crystal structures of (III), (V), (VII), and (IX) are determined by single crystal XRD. (V)·2.5DMF and (IX)·6MeCN crystallize in the space group P1 with Z = 2 and Z = 1, respectively. (III)·2MeCN crystallizes in the space group Pnma with Z = 4, and (VII)·2MeCN in the space group P21/n with Z = 2. In the oligonuclear compounds (VII) and (IX) silver and gold aggregation occurs under formation of metal-metal bonds. Furthermore, the germa-closo-dodecaborate exhibits a hitherto unknown μ3-bridging coordination mode connecting three Ag atoms in (IX). -(SCHUBERT, H.; DIMMER, J.-A.; KUECHLE, F.-R.; EICHELE, K.; WESEMANN*, L.; Inorg.
