“…covalently attached a perylene monoimide unit onto a {P 2 W 17 } cluster, whereby the organic chromophores undergo electron transfer reactions with the POM cluster under illumination, as the hybrid forms a relatively long‐lived radical anion 69. Finally it must be mentioned that POM frameworks can be functionalized by organoantimony moieties, which themselves bridge between two sandwiching {W 9 } clusters in [{PhSbOH} 3 (A‐α‐PW 9 O 34 ) 2 ] 9− 70…”

Polyoxometalates (POMs) are a subset of metal oxides that represent a diverse range of molecular clusters with an almost unmatched range of physical properties and the ability to form dynamic structures that can range in size from the nano- to the micrometer scale. Herein we present the very latest developments from synthesis to structure and function of POMs. We discuss the possibilities of creating highly sophisticated functional hierarchical systems with multiple, interdependent, functionalities along with a critical analysis that allows the non-specialist to learn the salient features. We propose and present a "periodic table of polyoxometalate building blocks". We also highlight some of the current issues and challenges that need to be addressed to work towards the design of functional systems based upon POM building blocks and look ahead to possible emerging application areas.

“…The first organoantimony(V)‐embedded heteropolyoxotungstate, [{PhSb V (OH)} 3 ( A ‐α‐P V W 9 O 34 ) 2 ] 9− , was synthesized by our group by a hydrothermal approach 9a. Three years later, we also succeeded in preparing the first three organoantimony(III)‐containing POMs, [(PhSb III ) 4 ( A ‐α‐Ge IV W 9 O 34 ) 2 ] 12− , [(PhSb III ) 4 ( A ‐α‐P V W 9 O 34 ) 2 ] 10− , and [{2‐(Me 2 NCH 2 )C 6 H 4 Sb III } 3 ( B ‐α‐As III W 9 O 33 )] 3− .…”

A family of three sandwich-type, phenylantimony(III)-containing tungstoarsenates(III), [(PhSb(III) ){Na(H2 O)}As(III) 2 W19 O67 (H2 O)](11-) (1), [(PhSb(III) )2 As(III) 2 W19 O67 (H2 O)](10-) (2), and [(PhSb(III) )3 (B-α-As(III) W9 O33 )2 ](12-) (3), have been synthesized by one-pot procedures and isolated as hydrated alkali metal salts, Cs3 K3.5 Na4.5 [(PhSb(III) ){Na(H2 O)}As(III) 2 W19 O67 (H2 O)]⋅41H2 O (CsKNa-1), Cs4.5 K5.5 [(PhSb(III) )2 As(III) 2 W19 O67 (H2 O)]⋅35H2 O (CsK-2), and Cs4.5 Na7.5 [(PhSb(III) )3 (B-α-As(III) W9 O33 )2 ]⋅42H2 O (CsNa-3). The number of incorporated {PhSb(III) } units could be selectively tuned from one to three by careful control of the reaction parameters. The three compounds were characterized in the solid state by single-crystal XRD, IR spectroscopy, and thermogravimetric analysis. The aqueous solution stability of sandwich polyanions 1-3 was also studied by multinuclear ((1) H, (13) C, (183) W) NMR spectroscopy. Effective inhibitory activity against six different kinds of bacteria was identified for all three polyanions, for which the activity increased with the number of incorporated {PhSb(III) } groups.

“…Searching for diorganoantimony(V) reagents that can be used for the syntheses of organoantimony polyoxometalates [12] in aqueous conditions we became interested in the chemistry of diorganoantimony(V) trihalides and onium diorganotetrahaloantimonates. Our previous related studies had focused on diphenylantimony tribromide and onium organoantimonates(III) [13][14][15].…”
