摘要

The structure of the title compound, C(13)H(14)O(2), a pentacycloundecane cage derivative, exhibits unusual Csp 3-Csp 3 single-bond lengths ranging from 1.505 (3) to 1.607 (2) A and strained bond angles as small as 88.7 (1)degrees and as large as 121.0 (2)degrees. 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.
