Assembly of polyoxometalate-based inorganic–organic compounds from silver–Schiff base building blocks: synthesis, crystal structures and luminescent properties

A novel polyoxometalate-based metal-organic compound constructed from an unprecedented [Ag8(Hpyttz)4(H2pyttz)2] cluster and an in-situ [VW12O40]3− anion

“…In previous reports, many multi-metallic organic subunits have been successfully synthesized, such as {Zn 6 (Zn)L 6 }, {Cu 9 (TBC4) 3 }, and {Ag(DATC) 6 } 8 [8-10]. Among the transition metals, silver is a good candidate for the assembly of multinuclear subunits due to its flexible coordination mode [11,12]. However, to our knowledge, reports on the multinuclear silver clusters modified POMs are still very limited.…”

Three 3D Metal-Organic Frameworks Constructed from Keggin Polyanions and Multi-nuclear AgI Clusters: Assembly, Structures and Properties

“…The IR spectra of compounds 1 -3 are shown in [24]. The bands at 1456 -1698 cm −1 are characteristic of the ptz − anions for 1, at 1460 -1698 cm −1 for 2 and at 1450 -1695 cm −1 for 3 [25].…”

A polyoxometalate-based inorganic–organic hybrid polymer constructed from silver-Schiff base building block and Keggin-type cluster: Synthesis, crystal structure and photocatalytic performance for the degradation of rhodamine B

“…In our previous report, a series of pyridyl-based polydentate Schiff base ligands have been used to construct POM-based compounds with silver ions [11][12][13]. Whereafter, we introduce the Schiff base ligand N,N 0 -bis(furan-2-ylmethylene)hydrazin L to obtain a 2D Wells-Dawson-based coordination polymer H 0.5 Ag 0.…”

“…Because of the large number of potential coordination sites of POMs, incorporating them into metal-organic species may facilitate the production of new architectures with fascinating structures and modified properties [6][7][8]. Among the transition metal cations adopted to construct POM/TMCs compounds, Ag(I) is an excellent candidate due to its large radius, a wide variety of coordination geometries, and special photophysical and photochemical properties [9][10][11][12][13][14], which can be employed for its ability to form bonds with different donors simultaneously. Several studies have addressed the use of different organic ligands, such as 2,2 0 -bipy, 4,4 0 -bipy and 1,10-phenathroline for the preparation of a range of Ag-POM-based structures [15].…”
