A binary system consisting of a ditopic planar pseudo-pincer ligand (qlca = quinoline-2-carbaldehyde (pyridine-2-carbonyl) hydrazone) coordinated to two metal centres affording [{Ru(bpy)₂}(μ-qlca)NiCl₂]Cl·4H₂O·CH₃OH (2) (bpy = 2,2′-bipyridine) is reported. The Ni²⁺ moiety acts as the electrocatalytic active site for CO₂ reduction to CO. The turnover frequency (TOF) increased from 0.83 s⁻¹ for [Ni(qlca)Cl₂] (3) to 120 s⁻¹ for 2, and the overpotential is 350 mV less than that for 3 due to the electronic influence of the {Ru(bpy)₂}²⁺ moiety on the catalytic active site.
