When the Tolman Electronic Parameter Fails: A Comparative DFT and Charge Displacement Study of [(L)Ni(CO)3]0/– and [(L)Au(CO)]0/+
In this study we have examined 42 [(L) M (CO) n]±/0 complexes (M= Ni and Au), including
neutral ligands, such as phosphines and carbenes, and anionic ones. For each complex, the …
