Abstract
In this paper, three new Ag(I) coordination compounds, namely, AgL(3-iso)2 (1), [Ag4L4(bipy)4]·bipy·CH3CN·6H2O (2) and [Ag10L8(hmt)10(H2O)4]·(L)2·15H2O (3) (where 3-iso=3-methylisoquinoline, bipy=4,4′-bipyridine, hmt=hexamethylenetetramine and L=4-chloro-benzenesulfonate anion), have been synthesized by varying the nitrogen-containing secondary ligands. In compound 1, Ag(I) atoms are coordinated by 3-iso ligands and L anion to generate a discrete molecular structure. For compound 2, when the 3-iso ligand was replaced by bipy, Ag(I) atoms of 2 are linked by bipy ligands to generate a 1D polymeric chain, which are further expanded to a double chain through Ag⋯Ag interaction. In 3, the hmt ligands connect Ag(I) atoms to give a undulate 2D layer. These results indicate that the nitrogen-containing secondary ligands play important roles in the structural formation of the Ag(I) complexes. Moreover, the luminescent properties, elemental analyses and IR spectroscopy of these compounds were also studied.
