In this article, a series of mixed-ligand Ag (i) coordination polymers, namely, Ag (L1) H (2) O (), Ag (2)(hmt)(2)(L1)(2) (), [Ag (HL2)] H (2) O (), [Ag (L2)(biim)][Ag (biim)] (), [K (5)(L3)(2)][Ag (H (2) O)(2)] (), [Ag (2)(L3)(3-iso)][Ag (3-iso)] 5H (2) O (), [Ag (3)(L3)(bipy)(3)(H (2) O)] 6H (2) O (), [Ag (3)(L3)(biim)(3)] H (2) O (), and [Ag (3)(L3)(hmt)(2)(H (2) O)(3)] H (2) O () (where hmt = hexamethylenetetramine, bipy = 4,4'-bipyridine, biim = 1,1'-(1,4-butanediyl)-bis (imidazole), 3-iso = 3-methylisoquinoline, L1 = 2,5-dichloro-4-amino-benzenesulfonate anion, L2 = 2-nitroso-1-naphthol-4-sulfonate anion and L3 = 4-hydroxy-5-nitro-1,3-benzenedisulfonate anion), have been synthesized by varying the anionic sulfonate-containing ligands and nitrogen-containing secondary ligands. Compounds and were synthesized through their parent compounds and , respectively, while were obtained by their parent compound . Ag (i) centers of are linked by L1 anions to generate a 1D polymeric chain, while Ag (i) centers of are bridged by hmt ligands to form a 2D polymeric layer. In , Ag (i) centers are connected by L2 anions to yield a 1D double chain, whereas Ag (i) centers in are joined by biim ligands and L2 anions, generating an unusual anionic chain and a cationic chain, respectively. In , Ag (i) centers are coordinated by water molecules, and K (i) cations are coordinated by L3 anions to form a pillared layered structure with inorganic layers and organic pillars. In , Ag (i) centers are coordinated by 3-iso ligands and L3 anions to generate a discrete molecular structure. In , bipy ligands bridge Ag (i) centers to give Ag-bipy chains, which are further linked by L3 anions to produce a 2D polymeric layer. In , Ag (i) centers are bridged by biim ligands to generate a 1D polymeric chain. In , the hmt ligands connect Ag (i) centers to give a binodal (3,4)-connected net with (6 (3))(6 (5).8)(2) topology. These results indicate that anionic sulfonate-containing ligands and the nitrogen-containing secondary ligands play important roles in the structural formation of the Ag (i) complexes. Additionally, the luminescent properties, elemental analyses and IR spectroscopy of these compounds were also studied. |
