has an Mn-HC 3-center 2-electron agostic interaction, have been analyzed with density
functional theory (DFT) computations. The fluxionality of this complex is a classic in
organometallic chemistry (as highlighted by its inclusion as a study problem in the textbook
by Kegley and Pinhas, Problems and Solutions in Organometallic Chemistry), and we
provide new insights into its chemistry. Besides the three previously reported fluxional …
