Abstract

The literature data on substituent influence on the ^51^V, ^55^Mn, ^57^Fe, ^59^Co, ^61^Ni, ^95^Mo, ^103^Rh, ^183^W, ^187^Os and ^195^Pt NMR chemical shifts (Ξ΄) and on J (M, P; M = Mn, Fe, Mo, Rh, W, Os) coupling constants have been analyzed for 30 series of the organometallic complexes. It has been established for the first time that the Ξ΄ and J values depend on the inductive, resonance and polarizability effects of substituents. The polarizability effect is caused by the partial charge on the central M atom. The contribution of this effect ranges from 3 to 86%. Copyright Β© 2009 John Wiley & Sons, Ltd.
