Q = O, S), containing a great variety of different organometallic groups containing transition or heavy main-group metals. The data on chemical hardness of L n M groups were obtained from NMR study of distribution of different L n M groups between hard and soft anions. The following basic results have been obtained. (1) The relative electronegativity and chemical hardness of L n M groups can change in parallel or not with the electronegativity and hardness of the central metal atom. (2) The substituents in Ar can substantially modify electronegativity and hardness of Ar n M groups; the influence of Ar groups has an inductive nature; the increase in electrondonating ability of aryl ligands enhances the hardness of Ar n M cations. (3) The relative electronegativity and hardness of L n M groups in L n MX are invariant and do not depend on X.

Two series of model compounds, Ar2BOC6H4F‐4 and Ar2B(Py)OC6H4F‐4, containing three‐and four‐coordinated boron atoms, have been synthesized. It was established by 19F NMR technique that both systems possess a similar transmissive ability that is in intermolecular coordination with pyridine does not influence the transmissive properties of the boron‐oxygen binuclear bridging group. The solvent polarity does not influence the electron transmission in the boron complexes studied.
