Crystal structure and Hirshfeld surface analysis of 4,5-di­bromo-2-(4-meth­oxy­phen­yl)-2,3,4,4a,5,6,7,7a-octa­hydro-1H-4,6-ep­oxy-1H-cyclo­penta­[c]pyridin-1-one

The mol­ecule of the title compound, C(15)H(15)Br(2)NO(3), comprises a fused tricyclic system consisting of two five-membered rings (cyclo­pentane and tetra­hydro­furan) and one six-membered ring (tetra­hydro­pyridinone). Both five-membered rings of the tricyclic system have envelope conformations, and the conformation of the six-membered cycle is inter­mediate between chair and half-chair. In the crystal, the mol­ecules are linked by C—H⋯O hydrogen bonds and C—H⋯π, C—Br⋯π and C⋯O inter­actions into double layers. The layers are connected into a three-dimensional network by van der Waals inter­actions.
