Abstract:
The compound [Na 2 (H 2 O) 2 Ni 2 (As 2 W 15 O 56 ) 2 ] 18– , Ni2As4, was synthesized and structurally characterized for the first time by X‐ray crystallography. This complex reacts with Fe III to form two new mixed‐metal sandwich‐type complexes, [Fe 2 (H 2 O) 2 Ni 2 (As 2 W 15 O 56 ) 2 ] 14– , Fe2_Ni2As4, and [Fe(H 2 O)Ni(H 2 O)Ni 2 (As 2 W 15 O 56 ) 2 ] 15– , FeNi_Ni2As4. In comparison, the synthesis of the previously reported complex [Na 2 (H 2 O) 2 Fe 2 (As 2 W 15 O 56 ) 2 ] 16– , Fe2As4, was rationalized and improved, and the incorporation of Ni II into the latter compound leads to the new mixed‐metal complex [Ni 2 (H 2 O) 2 Fe 2 (As 2 W 15 O 56 ) 2 ] 14– , Ni2_Fe2As4. Complete characterization of these complexes by FTIR, UV/Vis, elemental analysis, magnetic measurements and X‐ray crystallography, wherever possible, clearly defined their electronic and structural properties. These complexes undergo multiple electron‐transfer processes and are effective in the electrocatalytic reduction of nitrite, dioxygen and hydrogen peroxide.(© Wiley‐VCH Verlag GmbH & Co.
