A catalyst developed from a Cu II complex of (Et 4 N)[Cu(pyN 2 Me2 )(HCO 2 )]⋅0.5 CH 3 OH⋅H 2 O ( 1 ⋅0.5 CH 3 OH⋅H 2 O; pyN 2 Me2 =bis(2,6‐dimethylphenyl)‐2,6‐pyridinedicarboxamidate(2‐)) shows a high activity to catalyze the reduction reaction of CO 2 to CO driven by visible light in 4:1 acetonitrile/water ( v : v ) using [Ru(phen) 3 ](PF 6 ) 2 as photosensitizer and TEOA as sacrificial reductant, with a high TON of 9900 and a high CO selectivity of 98 %. The results of isotope labeling experiment, durability tests and energy dispersive spectroscopy reveal that 1 is robust during the photocatalytic process.
