Abstract

We present an Ir complex that extracts electrons from H₂ at room temperature and stores them as a H₂-derived energy carrier (H₂EC) at room temperature. Furthermore, we demonstrate that this complex reduces CO₂ to a metal–CO₂²⁻ species at room temperature, and present the first electrospray ionisation mass spectrum for this compound.
