Title: Direct experimental evaluation of ligand-induced backbonding in nickel metallacyclic complexes

Journal Article · · Faraday Discussions
DOI: https://doi.org/10.1039/C9FD00041K · OSTI ID:1564507

The details of ligand-induced backbonding in nickel diphosphine π complexes are explored using nickel L-edge (3d←2p) X-ray absorption spectroscopy as a means of quantifying the degree of backbonding derived from direct Ni 3d donation into the π ligand.
