Ligand Electrochemical Parameter Approach to Molecular Design. σ-Donation, π-Back Donation, and Other Metrics in Ruthenium(II) Dinitrogen Complexes

Abstract: Using the density functional theory, [(N 2 )Ru II L 5 ] n+ species are studied in silico. The properties of the Ru−N 2 bond are derived, including σdonation, π-back donation, Ru−N and N−N bond lengths and bond orders, net charges and NN stretching frequencies, and so forth. These data are correlated using the ligand electrochemical parameter (E L ) theory, whereby the availability of electrons in the [RuL 5 ] n+ fragment is defined by its electron richness, which is the sum of the E L parameters, ΣE L (L 5 ). … Show more

“…The additive electrochemical parameters of Lever can be used to estimate the extent of π backdonation for a wide range of Ru II complexes. 75 Of this series, only the group 6 metals can be protonated with strong acids such as HBr in THF to produce the hydrazido complexes [M(NNH 2 )(Br)L 4 ] + 52 (Fig. 18).…”
