Electrocatalytic reduction of CO2 using Mn complexes with unconventional coordination environments

Abstract

New complexes, Mn{κ³-[2,6-{Ph₂PNMe}₂(NC₅H₃)]}(CO)₃⁺Br⁻ (1⁺Br⁻) and MnBr{κ²-(Ph₂P)NMe(NC₅H₄)}(CO)₃ (2), are reported and present new ligand environments for CO₂ electrocatalytic reduction to CO. Compound 1⁺ presents a unique metal geometry for CO production (96%) in the absence of added water while 2 required addition of water and generated both CO and H₂ products.
