Abstract:
The structure of the title compound, C13H14O2, a pentacycloundecane
cage derivative, exhibits unusual Csp3—Csp3 singlebond
lengths ranging from 1.505 (3) to 1.607 (2) A ° and
strained bond angles as small as 88.7 (1) and as large as
121.0 (2) . In this meso compound, an internal non-crystallographic
mirror plane exists, bisecting the molecule. In the
crystal, weak C—H O hydrogen bonds link the molecules
into an infinite spiral about a twofold screw axis along the
[100] direction.
