Аннотация: (Rhodium trichloride reacts with 1,2-bis[(2,6-diisopropylphenyl)imino] acenaphthene (dpp-bian) to afford new octahedral complex mer-[Rh(dpp-bian)(H₂O)Cl₃]·CH₂Cl₂. The CV of mer-[Rh(dpp-bian)(H₂O)Cl₃] in MeCN shows an irreversible reduction that corresponds to the Rh^III/Rh^I couple, followed by reversible or quasi-reversible cathodic waves assigned to reduction of the dpp-bian ligand. DFT calculations confirm the assignment of the redox processes and predict the elimination of two chloride ligands from axial positions upon two-electron reduction of mer-[Rh(dpp-bian)(H₂O)Cl₃] with the formation of a Rh^I square-planar complex [Rh^I(dpp-bian)(H₂O)Cl].

Ключевые слова: rhodium, acenaphthene-1,2-diimines, crystal structure, cyclic voltammetry, DFT calculations, electrocatalyzed CO2 reduction.
