The amount of solvent (H2O) should be minimized because of the slight solubility of VOPO4.2H2O. The structurally analogous VOAsO4.2H2O ( N. G. Chernorukov, N. P. Egorov, I. A. Korshunov, Zh. Neorg. Khim. 23 (1978) 2672) reacts similarly to give brown intercalation compounds. Attempts at electrochemical intercalation were unsuccessful due to the low conductivity of both host materials and their intercalation compounds. 5 The compounds are generally quite crystalline. The layer spacings determined experimentally are equal to the tetragonal c axis or c/2 when cation order is present. The spacings depend on H2O activity, those presented in Table 1 being observed under ambient laboratory conditions. The x and n values are determined by microanalysis, redox titrimetry, and thermogravimetric analysis. Citing Literature Volume22, Issue5May 1983Pages 412-413 ReferencesRelatedInformation
