The multinuclear metal–ligand supramolecular synthon RC 6 H 4 C≡C⊃Ag n (R = Me, F; n = 3–5) has been employed to construct the two high-nuclearity silver ethynide cluster compounds [(NO 3 ) 2 @Ag 26 ( o -MeC 6 H 4 C≡C) 16 ](NO 3 ) 8 ·5H 2 O ( 1 ) and [NO 3 @Ag 15 ( o -FC 6 H 4 C≡C) 10 ](NO 3 ) 4 ( 2 ), which bear the same nitrate central core. The synthesis of [CrO 4 @Ag 18 ( i PrC≡C) 12 ](ClO 4 ) 4 ( 3 ) and [ClO 4 @Ag 18 ( i PrC≡C) 12 ](ClO 4 ) 5 ( 4 ) demonstrated the effect of variation of central anionic core size and charge on the construction of multidimensional organosilver(I) networks. The bulkiness of the peripheral ligands and the orientation of substituents with respect to the ethynide group proved to be dominant factors that direct the formation of high-nuclearity clusters and the assembly of coordination networks. To our knowledge, 1 and 2 are the first examples using the nitrate anion for templated cluster synthesis.
