摘要：

Molecules of the title compound, (+)-(1R,4R)-3-benzoyl-1,7,7-trimethylbicyclo[ 2.2.1] heptan-2-one, C17H20O2, crystallize in the diketo form. One of the carbonyl groups is involved in a weak intramolecular C-H center dot center dot center dot O interaction [C center dot center dot center dot O = 2.778 (3) angstrom]. 3-Benzoylcamphor is a rare example of a structurally characterized beta-diketone that crystallizes both in the diketo and the enol forms. According to density functional theory (DFT) calculations, the diketo tautomer is destabilized by 17.4 kJ mol(-1) over the previously reported [Niemeyer & Gan (2005). Acta Cryst. E61, o2363-o2365] enol form.
