π Backbonding in Carbonyl Complexes and Carbon–Oxygen Stretching Frequencies: A Molecular Modeling Exercise
Craig D. Montgomery
Department of Chemistry, Trinity Western University, Langley, BC V2Y 1Y1, Canada
Cover
January 2007
Vol. 84 No. 1
p. 102
Abstract
An exercise in molecular modeling, suitable for a third- or fourth-year course in organometallic or inorganic chemistry, is presented in which the effects of the metal center, the metal charge, and the electron-withdrawing properties of co-ligands upon the degree of π backbonding to carbonyl ligands are demonstrated. The ν CO values are calculated, along with C–O bond orders for a series of model compounds to demonstrate each effect. The calculated values are also compared with experimental ones.
