• Atomically dispersed Zn-anchored 3D sponge-like polymeric carbon nitride (Zn-PCN) characteristic of a unique Zn-N₆ electron-deficient configuration is synthesized via an intermediate coordination strategy.

• The electron-deficient Zn-N₆ configuration contributes to enhanced electron excitation, accelerated charge separation and transfer as well as reduced overpotentials of water redox reactions.

• The obtained Zn-PCN realizes photocatalytic overall water splitting to stoichiometrically produce H₂ and O₂ with good durability under visible light.
