Exo-π-bonding to an ortho-carborane hypercarbon atom: systematic icosahedral cage distortions reflected in the structures of the fluoro-, hydroxy- and amino-carboranes, 1-X-2-Ph-1,2-C2B10H10 (X = F, OH or NH2) and related anions†
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
