Abstract:
The title compound, C22H26O6, crystallized in the centrosymmetric space group Pbcn with half of the molecule as the asymmetric unit (the molecular symmetry is 2). The H atoms of each of the four methyl groups in the asymmetric unit are disordered over two sites. Nine leading C-H...O interactions are present, with H...O distances ranging from 2.50 to 2.87 A and C...O distances ranging from 3.157 (3) to 3.567 (3) A. The various interaction chains from a three-dimensional network. The intramolecular angle between the biphenyl ring planes (twist angle) is 71.3 (1) degree.

Stability of Substituted Cyclohexanes
The two chair conformations of cyclohexanes undergo rapid interconversion at room temperature. Both forms have identical energies and stabilities, each comprising equal amounts of the equilibrium mixture. Replacing a hydrogen atom with a functional group makes the two conformations energetically non-equivalent.
