| Abstract: | Three Ag(I) coordination complexes, namely [Ag3(2-stp)(2-apy)2·3H2O]n (1), [Ag3(2-stp)(2-apy)2]n (2) and [Ag3(2-stp)(3-apy)(H2O)]n (3) (2-NaH2stp = 2-sulfoterephthalic acid monosodium salt, 2-apy = 2-aminopyridine and 3-apy = 3-aminopyridine), have been synthesized and structurally characterized. They all show two-dimensional network structures. In complex 1, the Ag3 units are linked by stp ligands to form a 1D chain. Consequently, the 2-apy ligands link the adjacent 1D chain into 2D polymeric sheets. In 2, Ag1 and Ag2 atoms are bridged by stp ligands to form a 2D infinite sheet. In 3, the stp anion adopts a μ7-(η1,η2):(η1,η1,η0):(η1,η1) coordination mode to Ag3 units to 2D layer sheet and the network is consolidated by 3-apy ligands. The thermogravimetric analyses and photoluminescence of the complexes were also investigated. |
