Quadruple bonding between iron and boron in the BFe(CO)3 − complex
Abstract
While main group elements possess four valence orbitals that are accessible for bonding, quadruple bonding to main group elements is very rarely observed. Here the authors report that boron is able to form four bonding interactions with iron in the BFe(CO)3 - anion complex.
