Abstract

The photogeneration of X₂ is the key to achieving an efficient HX-splitting photocycle, as it is more thermodynamically and kinetically challenging than its H₂ half reaction counterpart. Here we report a strategy that enables Cl₂ photoelimination from low-valent binuclear d⁹–d⁹ and d⁹–d¹⁰ Ni complexes. We demonstrate the importance a of metal–metal bond interaction for M–X bond photoactivation with a combination of TD-DFT computations together with spectroscopy and photocrystallography, exemplifying a design principle for future developments of 3d metal complexes for HX photocatalysis.
