The factors affecting on the assembly of Ag–H2biim system: size, charge or shape of polyanions?

Assembly of three new POM-based Ag(I) coordination polymers with antibacterial and photocatalytic properties

“…Reported literatures have indicated that one of intriguing functions of Ag complexes is antibacterial activity and as drugs used in the field of pharmacy [50,51]. Therefore, the antibacterial experiments against negative E. coli and positive S. agalactiae were investigated.…”

Two Unusual 3D POM‐Ag Frameworks with Tetragonal and Dodecagonal Helical Channels

“…a) Ball-and-stick representation of 2D metal-organic sheets that stabilize helical channel along the b axis. In contrast, the rates of photocatalytic decomposition by insoluble (NBu 4 12 O 40 ] catalysts are 47.5 % and 43.3 %, respectively, after UV irradiation for 150 min, which shows that the formation of organic-inorganic hybrid compounds based on POMs could improve the photocatalytic performance of (NBu 4 ) 3 A C H T U N G T R E N N U N G [PW 12 O 40 ] and (NBu 4 ) 4 A C H T U N G T R E N N U N G [SiW 12 O 40 ]. c) Topology of the 2D metal-organic sheet.…”

“…[7] Until now, most of the reported helical POM-based compounds have been helical chains and examples with helical channels are very rare. [5, 6, 9a] So, the key to obtain-Abstract: Two new hybrid compounds with tetragonal and dodecagonal helical channels, KA C H T U N G T R E N N U N G [Ag 14 12 O 40 ] 2 ·H 2 O (2), have been hydrothermally synthesized and structurally characterized by using routine techniques. Compared with types I and II, compounds of type III have not yet been reported, perhaps because the flexible organic ligands form the spiral more easily than the robust inorganic POMs in the POM-metal-organic systems.…”

“…Herein, we report the synthesis and characterization of two hybrid compounds based on the three species mentioned above, that is, 12 …”

Synthesis, structure, and photocatalytic property of a new hybrid compound based on unusual bi-silver-capped polyoxometalates

“…However, the capping metals in these compounds were generally restricted to Mo or V atoms, except for the several examples (see the summarization of these compounds based on capped POMs in Table S1), in which the capping metals are Ni, Sb, Nb, As and Ag atoms. As is well known, Ag + ion is widely applied in luminescent, catalytic, and antibacterial materials [28,29]. Further, Ag + ion possesses flexible coordination geometries and high affinity to O and N donors, which may easily form covalent links between Ag + ions and POMs/ ligands [30].…”
