Three cases of aminobenzoic acid hybrid polyoxotungstates, Na3(H3O)2[(HPW6O21) (O2CC6H4NH2)3]·7H2O (1), K2(H3O)4[(AsW6O21)(O2CC6H4NH2)3]·4H2O (2), and [(H2N(CH3)2]3Na2(H3O)[(SbW6O21) (3), were successfully synthesized. This is the first report successful assembly hexanuclear {XW6} (X = HPIII, AsIII, or SbIII) clusters organic carboxylic (para acid) ligands. All three hybrids feature a common unit composed six-membered {WO6} octahedral ring capped by one {XO3} trigonal pyramid. Furthermore, these possess an extensive three-dimensional network hydrogen bonds, which not only provide high thermal stability but also contribute to excellent proton conductive performances. Simultaneously, based on Hirshfeld partition analysis, combined with interaction between POMs water molecules, transport mechanisms highlighted.

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".
