ABSTRACT:
Proposed is a method for the preparation of an ionic polyhalogeno metal complex compound consisting of a tetraalkylammonium cation and a polyhalogeno metal anion, of which the metal is selected from those having an atomic valency of 1 and a coordination number of 2, those having an atomic valency of 3 and a coordination number of 4 and those having an atomic valency of 2 and a coordination number of 4. The method comprises the steps of: dissolving a tetraalkylammonium halide and elementary halogen in a stoichiometric proportion corresponding to the chemical composition of the desired complex compound in an organic solvent to form a solution; dissolving, in the solution, the metal in an amount larger than the stoichiometric amount so as to be dissolved in the solution forming the complex compound in the reaction mixture; removing the undissolved metal from the reaction mixture to give a solution of the complex compound; and isolating the complex compound from the solution.
