We have successfully synthesized K17{[{KIn2(μ-OH)2}(α,α-Si2W18O66)]2[In6(μ-OH)13(H2O)8]}·35H2O (potassium salt of In10-open), an open-Wells–Dawson polyoxometalate (POM) containing ten indium metal atoms. This novel compound was characterized by X-ray crystallography, 29Si NMR, FTIR, complete elemental analysis, and TG/DTA. X-ray crystallography results for {[{KIn2(μ-OH)2}(α,α-Si2W18O66)]2[In6(μ-OH)13(H2O)8]}17− (In10-open) revealed two open-Wells–Dawson units containing two In3+ ions and a K+ ion, [{KIn2(μ-OH)2}(α,α-Si2W18O66)]11−, connected by an In6-hydroxide cluster moiety, [In6(μ-OH)13(H2O)8]5+. In10-open is the first example of an open-Wells–Dawson POM containing a fifth-period element. Moreover, to the best of our knowledge, it exhibits the highest nuclearity among the indium-containing POMs reported to date. View Full-Text
