Abstract

The structures of derivatives of phenyl-ortho-carborane bearing on the second cage hypercarbon atom a π-donor substituent (F, OH, O−, NH2, NH− and CH2−) were investigated by NMR, X-ray crystallography and computational studies. The molecular structures of these compounds, notably their cage C1–C2 distances and the orientations of their π-donor substituents (OH, NH2, NH− and CH2−) show remarkable and systematic variations with the degree of exo π-bonding, which varies as expected with the π-donor characteristics of the substituent.
