Two novel arsenotungstate species, [As4W48O168]36– (1a) and [As2W21O77(H2O)3]22– (2a), have been successfully isolated under a one-pot synthetic method. 1a is the second largest cluster constructed from four {AsW12} clusters combined together. 2a can be described as lacunary sites of {As2W19} filled by {W2O8} units. Compounds 1 2 exhibit proton conductivity properties, value 5.0 × 10–3 S cm–1 at 98% relative humidity 75 °C. This work proves that lattice water molecules polyoxoanions participate in formation hydrogen bond, acting effective pathway for intermolecular conduction.

The development of solid-state proton conductors (SSPCs) is significant interest for their deployment as exchange membranes in fuel cell (PEMFC) technology. aqueous medium synthesis with ample intrinsic sources has made crystalline polyoxometalates (POMs) promising SSPCs over others. Herein, we aim to showcase the solitary POMs and hybrids (with polymers MOFs/COFs) by organizing them based on approaches taken up (intrinsic or extrinsic) install various protonic while positioning within specific components POM frameworks. Particular attention paid a critical discussion whether conductivity purely combination other ionic (majorly originating from charge balancing counterions) thus recommend terminology be used. "Critical Discussion" section provides in-depth insights which are often overlooked, future recommendations "Future Outlook".

Abstract Exploring efficient heterogeneous catalysts for catalytic oxidation of chemical warfare agents (CWAs) is highly desired. As a class discrete anionic metal oxide clusters, polyoxometalates (POMs) provide abundant active sites, thus resulting their rich redox properties. Here, family known POM‐incorporated Cu I ‐resorcin[4]arene metal‐organic complexes, namely, [Cu 4 (TPTR4A) 2 ][PW 12 O 40 ](OH) ⋅ 0.5DMA 5H ( ‐ PW ), (TPTR4 A) ][PMo 2DMA H PMo ) and ][SiW ] 2.5DMA SiW were utilized as to promote the 2‐chloroethyl ethyl sulfide (CEES). Strikingly, compared novel compound 3 Cl 6 (TPTR4A)(DMA)] CH OH (defined T three complexes exhibited excellent stability, indicating that integration POMs metal–organic units could improve stability compounds. Moreover, showed higher activities CEES CEESO with selectivities both 99 %.
