Barriers to rotation about the preferred axis, C‐4HgC‐4′, were determined for diphenyl‐, bis( o ‐tolyl)‐ and bis( m ‐tolyl)‐mercury from 13 C T 1 relaxation times as a function of temperature in DMSO and in 1,1,2,2‐tetrachloroethane–CCl 4 . Based on results for the unsymmetrical compound phenyl( o ‐tolyl)mercury, the rotation about the preferred axis is interpreted as rotation about the carbon–mercury bond. The average barrier to internal rotation of 3.6 ± 0.6 kcal mol −1 is constant as a function of both methyl substitution and coordinating and non‐coordinating solvents.
