1,7-Dimethyl­penta­cyclo­[5.4.0.0(2,6).0(3,10).0(5,9)]undecane-8,11-dione

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) Å and strained bond angles as small as 88.7 (1)° and as large as 121.0 (2)°. In this meso compound, an inter­nal non-c...

description 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) Å 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.
