Abstract

This article describes the structural authentication of a unique triply bridged [1](ClO₄)₂ and monomeric [2]ClO₄/[3]ClO₄. Electrochemical HER on a carbon cloth support demonstrated the superior performance of [1](ClO₄)₂ with high TON (>10⁵) and its long-term stability. The primary kinetic isotope effect of [1](ClO₄)₂ revealed the involvement of PCET in the rate-determining step.
