Metal Catalysis Acting on Nitriles in Early Earth Hydrothermal Systems
Life, 2023 Hydrothermal systems are areas in which heated fluids and organic molecules rush through basaltic material rich in metals and minerals. By studying malononitrile and acetonitrile, we examine the effects of metal and mineral nanoparticles on nitrile ...

A Comprehensive Analysis of the Metal–Nitrile Bonding in an Organo-Diiron System
Molecules, 2021 Nitriles (N≡CR) are ubiquitous in coordination chemistry, yet literature studies on metal–nitrile bonding based on a multi-technique approach are rare. We selected an easily-available di-organoiron framework, containing both π-acceptor (CO, aminocarbyne)
