Abstract
New procedure for synthesis of isostructural sodium heteropoly decatungstolanthanidates(III) with Peacock–Weakley type anion Na9[Ln(W5O18)2]·35H2O (Ln = La–Yb) in Ln(NO3)3 – Na2WO4 – HNO3 – H2O solutions with a ratio ν(Ln) : ν(W) = 1:10, acidified up to Z = ν(HNO3)/ν(Na2WO4) = 0.80, were elaborated (Mariichak O.Yu., et al. Patent of Ukraine No. 121322, 2017). The synthesized salts were characterized by Single Crystal X-ray analysis (Fig. 1), FT-IR and FT-Raman spectroscopy, and scanning electron microscopy.
