Stable Hydrogen Energy Carrier That Stores One Electron in a Cobalt(I) Complex for More Than 3 Months
This paper details a next-generation Co(I)-based hydrogen energy carrier (H2EC) that can readily extract one electron from hydrogen, store the electron for more than 3 months, and use the electron elsewhere when needed. It is noteworthy that the ability of the Co(I) complex to perform reductive coupling is much higher than that of a similar Ni(I) complex that we recently reported. Three X-ray structures are presented: the Co(II) complex before reaction with H2, the Co(I) complex after reaction with H2 (i.e., the H2EC), and a Co(III) chloromethyl complex formed by oxidative addition of dichloromethane to the Co(I) complex.
期刊介绍：
Organometallics is the flagship journal of organometallic chemistry and records progress in one of the most active fields of science, bridging organic and inorganic chemistry. The journal publishes Articles, Communications, Reviews, and Tutorials (instructional overviews) that depict research on the synthesis, structure, bonding, chemical reactivity, and reaction mechanisms for a variety of applications, including catalyst design and catalytic processes; main-group, transition-metal, and lanthanide and actinide metal chemistry; synthetic aspects of polymer science and materials science; and bioorganometallic chemistry.
