The development of an earth‐abundant, first‐row water oxidation catalyst that operates at neutral pH and low overpotential remains a fundamental chemical challenge. Herein, we report the first nickel‐based robust homogeneous water oxidation catalyst, which can electrocatalyze water oxidation at neutral pH and low overpotential in phosphate buffer. The results of DFT calculations verify that the OO bond formation in catalytic water oxidation prefers a HOOH coupling mechanism from a cis ‐isomer of the catalyst.
