Abstract

The novel basket-shaped three-electron-reduced heteropoly blue [H2dmpip]5[K [subset or is implied by] P6Mo18O73] was prepared and characterized; it shows reversible one-electron redox properties.

A Basket‐Like [Sr⊂P6MoV4MoVI14O73]10– Polyoxoanion Modified with {Cu(phen)(H2O)x} (x = 1–3) Fragments: Synthesis, Structure, Magnetic, and Electrochemical Properties

“…It is interesting that the cavity size of the basket‐like polyoxoanion seems to be more inclined to capture larger cations (Sr 2+ ) although both Sr 2+ and Na + ions coexist in the reaction system with similar concentrations. Zhang et al have also reported a similar [P 6 Mo 18 O 73 ] 11– polyoxoanion encapsulating a K + ion 13. The incorporation of these large cations may vice versa stabilize the whole cryptand polyoxoanion 18…”

“…[2b,2c,10–12] It is interesting that most of these hybrid compounds are based on inorganic {PMo 12– x TM x O 40 },10 {P 4 Mo 6 O 31 },11 and {P 2 Mo 5 O 23 }12 building blocks. More recently, three unusual large clusters, [P 6 Mo 18 O 73 ] 11– ,13 [H 14 (Mo 16 O 32 )Co 16 (PO 4 ) 24 (H 2 O) 20 ] 10– ,14 and [Na 4 (H 2 O) 6 {(Mo 2 O 4 ) 10 (P 2 O 7 ) 10 (OAc) 8 (H 2 O) 4 }] 24–[15] have been reported. However, no organic or metal–organic complexes have been successfully coordinated to these highly reduced polymolybdophosphate clusters so far, the reason for which may be that the large size of these POMs decreases the electron density of the surface or the coordination ability of the surface oxygen atoms.…”

Assembly of a basket-like {Sr ⊂ P6Mo18O73} cage from 0D dimmer to 2D network and its photo-/electro-catalytic properties

“…1). 15,16 In fact, the incorporation of these large cations may stabilize the whole cryptand polyoxoanion. The {P 4 Mo 4 } unit consists of four {MoO 6 } octahedra and four {PO 4 } tetrahedra, which are corner-linked together to form the "handle" of the basket.…”

High-efficiency photo- and electro-catalytic material based on a basket-like {Sr⊂P6Mo18O73} cage

“…It is proved that the cavity size of the basket-like polyoxoanion inclined to capture larger alkali metals or alkaline earth cations. 32,33 In fact, the incorporation of these large cations may vise versa stabilize the whole cryptand 25 polyoxoanion. All bond lengths and bond angles are in the normal range.…”
