title: 2,10-Dihydr-oxy-13-methyl-13-aza-tetra-cyclo-[9.3.1.0.0]penta-deca-3(8),4,6-triene-9,15-dione.
abstract: In the title compound, C(15)H(15)NO(4), the n-methyl-piperidone ring adopts a chair conformation and both five-membered rings adopt a twist conformation. An intra-molecular O-H⋯O hydrogen bond is observed. Inversion-related mol-ecules are linked into R(2) (2)(10) dimers by pairs of O-H⋯O hydrogen bonds. The crystal structure is further stabilized by C-H⋯O hydrogen bonds.
