The oxidative dissolution of transition metals in organic and aqueous organic media yields a broad range of complexes. In work, data are given on the dissolution of Ti, Zr, Nb, Ta, Cr, and Mn in HF-DMF and HF-DMF-H/sub 2/O/sub 2/ systems. The dimethylammonium oxyfluoride complexes were isolated and characterized. Metals of groups IV-VI may be oxidized in HF-DMF and HF-DMF-H/sub 2/O/sub 2/ systems. The dimethylammonium oxyfluoride complexes of titanium(IV), zirconium(IV), niobium(V), tantalum(V), and the oxyfluorides of chromium(III) and manganese(II) were isolated and characterized.
