New Sb₁₂ and Sb₁₄ Polyoxometalate Frameworks Derived from Arylstibonic Acids: [LiH₃(p-MeC₆H₄Sb)₁₂O₂₈]⁴⁻ and [BaH₁₀(p-MeC₆H₄Sb)₁₄O₃₄]
New Sb₁₂ and Sb₁₄ Polyoxometalate Frameworks Derived from Arylstibonic Acids: [LiH₃(p-MeC₆H₄Sb)₁₂O₂₈]⁴⁻ and [BaH₁₀(p-MeC₆H₄Sb)₁₄O₃₄]
Abstract
The lithium salt of p-tolylstibonic acid contains the anion [LiH₃(p-MeC₆H₄Sb)₁₂O₂₈]⁴⁻, in which the Li⁺ is fully enclosed within an {Sb₁₂O₂₈} cage with γ Keggin ion geometry; the idealized overall formula is Li₅[LiH₃(p-MeC₆H₄Sb)₁₂O₂₈]Br•18H₂O. In contrast, Ba²⁺ induces the formation of the unprecedented {Sb₁₄O₃₄} bowl-shaped polyoxostibonate [BaH₁₀(p-MeC₆H₄Sb)₁₄O₃₄]•4H₂O. Compounds were characterized by single-crystal X-ray crystallography and by ESI-MS.
