Abstract
The structure of the title compound, C(26)H(29)NO(7), at 173 K has an inter-molecular N-H⋯O hydrogen bond. This is one of the few examples where a mono-ketone penta-cyclo-undecane (PCU) mol-ecule exibits hydrogen bonding in the solid state. The dihedral angles of the amide and ester groups are normal and unaffected by the cage structure. A longer than normal C-C bond [1.571 (4) Å] was found within the cage structure.
