Reaction of (NH₄)[NbO(C₂O₄)₂(H₂O)₂]·3H₂O with K₁₂[H₂P₂W₁₂O₄₈]∙24H₂O in aqueous solution at pH 1.7 leads to the formation of mixed Nb/W species based on [(P₂M₁₈O₆₀)₂(µ-O)₂]ⁿ⁻ (M is a Nb/W mixture, when Nb ratio ranges from 6 to 8 and charge differs from 14- to 16- correspondingly) archetype. Direct crystallization from the reaction media results in colorless crystals with the composition formulated as K₉(NH₄)₅[cis-(P₂W₁₅Nb₃O₆₁)₂]·48H₂O (1). Crystallization in the presence of (NMe₂H₂)Cl yields two phases (2a and 2b), containing the same [trans-(P₂W_14.7Nb_3.3O₆₁)₂]^14.6− anions but different cation/H₂O compositions. Both phases are present in a mixture with bulk composition corresponding to (NMe₂H₂)_14.6[P₂W_14.7Nb_3.3O₆₁]₂·28H₂O (2). The solution behavior of 1 and 2 was studied with HR-ESI-MS and HPLC-ICP-AES. During XRPD study of 2 we found blue coloration of the thin film of the complex. This effect has only surface nature and was studied by diffuse reflectance spectra.
