P. G. Jones, H. Hopf and J. Hillmer

Abstract: The molecule of the title compound, C₂₀H₂₀O₂, displays crystallographic twofold symmetry. The bridgehead bond lengths are 1.584  (3) and 1.590  (3)  Å. There is slight distortion at one bridgehead C atom [C2-C3-C4 124.71  (13)° in standard cyclophane numbering]. The molecules are linked by a weak hydrogen bond of the form C-HO to form a layer structure.
