Silver(I)−Ethynide Clusters Constructed with Phosphonate-Functionized Polyoxovanadates

Two neutral silver(I)−phenylethynide clusters incorporating the [(tBuPO3)4V4O8]4− unit as an integral shell component, namely {(NO3)2@Ag16(CCPh)4[(tBuPO3)4V4O8]2(DMF)6(NO3)2}·DMF·H2O and {[(O2)V2O6]3@Ag43(CCPh)19[(tBuPO3)4V4O8]3(DMF)6}·5DMF·2H2O, have been isolated and characterized by X-ray crystallography. The central cavities of the Ag16 and Ag43 clusters are occupied by two NO3− and three [(O2)V2O6]4− template anions, respectively.
