High-Nuclearity Silver Thiolate Clusters Constructed with Phosphonates

The n-butylphosphonate ligand has been employed to construct three new silver(I) thiolate compounds. Singlecrystal X-ray analysis revealed that complexes 1 and 2 are Ag-48 and Ag-51 coordination chain polymers, while 3 contains a discrete Ag-48 cluster, in which three different kinds of silver(I) thiolate cluster shells enclose three different phosphonate- functionalized silver(I) cluster cores, respectively. The structures of clusters in 1-3 feature three three-shell arrangements, S@Ag-12@(nBuPO(3))(9)@Ag36S23, S@Ag-11@(nBuPO(3))(7)-(MoO4)(2) @Ag40S27 and MoO4@Ag-12@(nBuPO(3))(8)S-6 @Ag36S24, respectively.
