Chlorides mixed halides

Mixed Halide Alkoxides. Metal chlorides, hydrogen chloride, and carboxyUc acid chlorides convert metal alkoxides to metal chloride alkoxides. 

The mixed halide structure, for which the composition was refined to [(Zr6B)Clii.47(2)ll,, 53], crystallizes in the tetragonal space group P42/mnm, contrary to the only-chloride parent-type, which crystallizes orthorhombically [17]. This increase of symmetry is achieved through a random iodine substitution of 19.1(3)% of the Cl4 -site. Thereby the Zr3CF -units become planar, as can be seen from Fig. 5.5. 

In the method proposed by van Staden for the determination of three halides, these are separated in a short colunm packed with a strongly basic ion-exchange resin (Dowex i-X8) that is placed in an FI manifold. A laboratory-made tubular silver/silver halide ion-selective electrode is used as a potentiometric sensor. Van Staden compared the response capabilities of the halide-selective electrodes to a wide concentration range (20-5000 pg/mL) of individual and mixed halide solutions in the presence and absence of the ion-exchange column. By careful selection of appropriate concentrations of the potassixun nitrate carrier/eluent stream to satisfy the requirements of both the ion-exchange column and the halide-selective electrode, he succeeded in separating and determining chloride, bromide and iodide in mixed halide solutions with a detection limit of 5 /xg/mL [130].

The reaction of bis[trifluoromethyl] tellurium with chlorine fluoride at — 78° with fluorotrichloromethane as solvent first produced his[trifluoromethyl] tellurium chloride fluoride. When the reaction mixture was concentrated, the l9F-NMR signal of the chloride fluoride disappeared and was replaced by signals for bis[trifluoromethyl] tellurium difluoride and bis[trifluoromethyl] tellurium dichloride2. The diorgano tellurium dihalides reported in the literature as mixed dihalides might be mixtures of symmetrical dihalides. All mixed halide species were identified by 125Te- and 19F-NMR spectroscopy in dimethylformamide solutions prepared from equimolar amounts of two different tellurium dihalides3. 

Add solid potassium or ammonium peroxodisulphate to the solution of the mixed halides contained in a conical flask strongly acidify with dilute sulphuric acid heat the flask to about 80°, and aspirate a current of air through the solution with the aid of a filter pump (see Fig. IV.2 in Section IV.45, 5) until the solution is colourless. Add more solid peroxodisulphate or water as may be found necessary. Test the residual colourless liquid for chloride with silver nitrate solution and dilute nitric acid. 

Mixed pentahalides, PF5 X (X = Cl, Br, 1), are known but only the chlorides PF4CI, PF3CI2, PF2CI3, and PF3Br2 are well characterized as molecular species. Many of the other mixed halides are complex salts or mixtures of complex salts of the type PX4+X- and PX4+ PXg. ...
