Crystal structure of 4-bromo-5,7-dimeth­oxy-2,3-di­hydro-1H-inden-1-one

In the title mol­ecule, C₁₁H₁₁BrO₃, the di­hydro­indene moiety is essentially planar but with a slight twist in the saturated portion of the five-membered ring. The meth­oxy groups lie close to the above plane. In the crystal, π-stacking inter­actions between six-membered rings form stacks of mol­ecules extending along the a-axis directions, which are linked by weak C—H⋯O and C—H⋯Br hydrogen bonds.

A Hirshfeld surface analysis was performed showing H⋯H, O⋯H/H⋯O and Br⋯H/H⋯Br contacts make the largest contributions to inter­molecular inter­actions in the crystal.
