title: (+-)-12-Oxotricyclo[6.2.2.0(1,6)]dodecane-10-carboxylic acid: hydrogen bonding in a tricyclic delta-keto acid.
abstract: The ring system of the title compound, C(13)H(18)O(3), was synthesized by addition of ethyl acrylate to the dienamine of 2-octalone. The keto acid aggregates in the solid as acid-to-acid dimers [O...O = 2.663 (2) A and O[bond]H...O = 170 (3) degrees ] whose centrosymmetric hydrogen bonds lie across the a edges and the center of the chosen cell. Three intermolecular C[bond]H...O close contacts within 2.7 A were found involving the ketone group.
