Hexameric polyoxotantalate with proton conduction properties

Abstract

The first Fe-implanted polyoxotantalate (POTa), K12Na14H7.4[Fe10.7Ta1.3O8(OH)8(H2O)2(Ta6O19)6]·114.5H2O (1), has been obtained by self-assembly in alkaline solution. The polyanion consists of six Lindqvist-type {Ta6} units linked together by {Fe10.7Ta1.3}. The compound not...

Two resistance-switchable hybrid polyoxotantalates based on {Co2Ta12} clusters

“…29–31 To date, only a tiny number of POTas have been discovered. 32–47 The reasons for the limited development of POTas include the chemical inertness of the tantalite species, the lack of soluble POTa precursors, the narrow reaction pH range (10–12), the low aqueous solubility of the common [Ta 6 O 19 ] 8− precursor, and the chemical incompatibility between POTas and other metal cations. It is worth noting that POTas have been shown to have significant application value in the fields of virology, photocatalysis, proton conductivity and base catalysis.…”

The assembly of [Mo2O2S2]2+ based on polydentate phosphonate templates and their proton conductivity

“…[5][6][7][8] In this regard, polyoxometalates (POMs) have emerged as inherent molecular-based proton conductors, distinguished by their exceptional proton conductivity, tunable properties, solubility, and resilience to high temperatures. [9][10][11][12][13] Achieving the precise synthesis and functionalization of polyoxometalates poses a considerable challenge. Researchers have harnessed high-resolution mass spectrometry techniques to investigate cluster assembly patterns and control the assembly of oligomer building blocks.…”
