A substituted derivative of hexaphenylethane, hexakis(3,5-di-t-butylphenyl)ethane, has however been prepared. It features a very long central C–C bond at 167 pm (compared to the typical bond length of 154 pm). Attractive London dispersion forces between the t-butyl substituents are believed to be responsible for the stability of this very hindered molecule.[2]
