Ammonium hexachlororuthenate is the ammonium salt of hexachlororuthenic acid .

Extraction and presentation

Ammonium hexachlororuthenate (IV) can be obtained by adding a stoichiometric amount of ammonium chloride to a solution obtained by introducing ruthenium (VIII) oxide and chlorine into a dilute hydrogen chloride solution .

properties

(NH ₄ ) ₂ [RuCl ₆ ] forms deep dark red crystals which are sensitive to hydrolysis and which always contain some ammonium pentachlorohydroxoruthenate (IV) (NH ₄ ) ₂ [RuCl ₅ (OH)].

use

Ammonium hexachlororuthenate is an intermediate product in the recycling and recovery of ruthenium . Here, ammonium hexachlororuthenate is obtained from a ruthenium-containing solution and the metal is produced from the sparingly soluble ammonium hexachlororuthenate by calcination and, after several process steps, by reduction with hydrogen .
