The electrochemical behaviour of iridium and ruthenium in low-temperature melts based on carbamide and acetamide was studied. It was shown that the electrochemical dissolution of metals in the mentioned melts is accompanied by passivation and results in the formation of Ir(III) and Ru(III) ammonia complexes, which are discharged to the metal irreversibly in one  step. The stationary electrolysis of carbamide and acetamide melts leads to the deposition of metal on the metallic substrates (Pt, Cu, Mo) in the form of microcrystalline electroplating.
