Recent developments in the crystal engineering of diverse coordination modes (0–12) for Keggin-type polyoxometalates in hybrid inorganic–organic architectures

Synthesis, crystal structure, thermal analysis and dielectric properties of [(C4H9)4N]3Bi2Cl9 compound

“…Among them, the anionic M 2 X 9 3À sublattice is generally made up of: (i) one dimensional zigzag chains [12], (ii) two-dimensional layers [13,14], (iii) discrete bioctahedrals [15][16][17]. Indeed, the type of anionic form in these hybrids is clearly associated with the size and symmetry of both organic cations and the type of halogen atoms [18,19]. The experimental studies on many halogenometalates based on various alkylammonium cations like ethylammonium [20,21], metylammonium [22,23] and propylammonium have exhibited interesting dynamics of the alkylammonium groups.…”

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

“…On the other hand, polyoxometalates (POMs), a large family of early transition metal oxide clusters, can be used as secondary building units (SBUs) to construct higher dimensional coordination polymers, owning to the plenty of potential coordination sites. Furthermore, the versatile properties of POMs can be introduced into the final framework to prepare multifunctional materials [9][10][11][12][13][14][15]. Thus, POMs-based polynuclear silver CPs are worth developing to prepare new materials with desired properties.…”

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

“…One of the effective strategies in the construction of POM-based composites is to functionalize POMs with transition-metal compounds (TMCs) [4,5]. 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.…”
