Аннотация

Reactions of inorganic macrocyclic polytungstate cavitands K₂₈Li₅H₇[P₈W₄₈O₁₈₄]·92H₂O or Li₁₇(NH₄)₂₁H₂[P₈W₄₈O₁₈₄]·85H₂O with (NH₄)[NbO(C₂O₄)₂(H₂O)₂]·3H₂O (Nb-Ox) in aqueous solution lead to incorporation of up to five {NbO(H₂O)}³⁺ units into the {P₈W₄₈} cavity. The most stable species contain four {NbO(H₂O)}³⁺ units. The uptake of {NbO(H₂O)}³⁺ was determined by corroborative methods including single crystal XRD, inductively coupled plasma atomic emission spectroscopy (ICP-AES), ³¹P and ¹³C nuclear magnetic resonance (NMR), C-H-N elemental analysis (EA) and thermal gravimetric analysis (TGA). Solution speciation of the Nb-encapsulating macrocycles was studied by HPLC-ICP-AES and small angle X-ray scattering (SAXS).
