A dl-alanine covalently bonded giant arsenotungstate, namely, Na3Ba11H16[(AsW9O33)6{W2O5(H2O)(dl-Ala)}2{W3O6(H2O)(dl-Ala)}2{W2O5(dl-Ala)}] (1; dl-Ala = dl-alanine), has been synthesized and is composed of six [AsW9O33]9- fragments fused together via two [W2O5(H2O)(dl-Ala)]+ segments, two [W3O6(H2O)(dl-Ala)]5+ segments, and a [W2O5(dl-Ala)]+ segment. This complex represents the first carboxylate-based hybrid polyoxotungstate without the introduction of lanthanide ions. Besides, compound 1 demonstrates not only fast photochromic properties but also interesting proton conductivity properties, with an achieved conductivity of 2.830 × 10-4 S·cm-1 (65 °C, 75% relative humidity).
