| Abstract: | Variation of the reaction conditions with AgC??CR (R?=?Ph, t Bu), t BuPO3H2, (Et4N)VO3 and AgNO3 as starting materials afforded three isostructural globular neutral silver(I)-ethynide clusters incorporating the ( t BuPO3)4V4O8]4? unit as an integral shell component, namely {(NO3)2@Ag16(C??CPh)4( t BuPO3)4V4O8]2(DEF)6(NO3)2}, {(NO3)2@Ag16(C??C t Bu)4( t BuPO3)4V4O8]2(DMF)6(NO3)2}·DMF·2H2O and {(NO3)2@Ag16(C??C t Bu)4( t BuPO3)4V4O8]2(DMF)6(NO3)2}·{(NO3)2@Ag16(C??C t Bu)4( t BuPO3)4V4O8]2(DMF)4(py)2(NO3)2}·DMF·5H2O, in which the central cavity of each Ag16 cluster is occupied by two nitrate ions that function as a template. Furthermore, from the reaction of AgC??C t Bu with (NH4)4V2O4(d,l-citrate)2]·4H2O, we isolated a new high-nuclearity silver(I)-ethynide cluster (VO4)2@Ag34(C??C t Bu)22(NO3)6]·8H2O that encapsulates a pair of templating orthovanadate ions. |
