Abstract

4-Ethynylpyridine and 5-ethynylpyrimidine were utilized as ligands to synthesize three novel silverethynide complexes [(4-Py-C2Ag)3·6CF3CO2Ag·2H2O] (1), [(4-Py-C2Ag)2·4AgNO3] (2) and [(5-Pyrim-C2Ag)·3AgNO3·H2O] (3). In both 1 and 2, the [4-C5H4N(C[triple bond, length as m-dash]C)Ag4]3+ units aggregate to generate linear silver chains through silverethynide and argentophilic interactions, which are further connected through AgN(pyridyl) coordination bonds to afford 2D grids, and finally linked by trifluoroacetate or nitrate groups to form a rigid 3D coordination network. However in 3, each [5-C4H3N2(C[triple bond, length as m-dash]C)Ag4]3+ unit interacts with two other units through AgN(pyrimidyl) bonds to construct 2D honeycomb-like networks, and are also further connected by nitrate groups to generate a 3D network. It is demonstrated that the coordination modes of organic ligands play a key role in controlling the structures of the organometallic networks based on silverethynide complexes.
