外文摘要：Binary polyantimony clusters,namely[Cu2Sb14]4-and[Ag2Sb14]4-,containing coinage metals,were successfully synthesized and characterized,in which two homoatomic Sb73-subunits are bridged by two coinage metals in η4∶η1 and η1∶η1 coordination modes,respectively.In[Cu2Sb14]4-,two bridging Cu ions and two Sb atoms form a planar rhombic unit,which was revealed to have antiaro-matic properties by theoretical calculations.Further electron structure and bonding analysis confirmed the presence of delocalized bonds in the rhombic unit and the metallophilic interaction between two formal M+ions.
