Polyoxometalate-mediated syntheses of three structurally new silver clusters.

Three structurally new polyoxometalate-templated silver clusters, homometallic [(SiWO)@Ag(PrS)(DPPP)Cl](SiWO) (Ag), heterometallic [(SiWO)@AgCu(PrS)(DPPP)Cl](SbF) (AgCu) and {Ag(PrS)(DPPP)(CHCOO)[Co(OH)(HO)SiWO]}·(CHCN) (AgCo) (PrS = isopropanethiolate, DPPP = 1,3-bis(diphenylphosphino)propane, SbF = hexafluoroantimonate) have been successfully synthesized using a facile solvothermal approach. The introduction of copper and cobalt ions can induce obvious changes in the molecular configuration of the obtained clusters, leading to distinct temperature-dependent photoluminescence and photothermal conversion properties.
