Description
Summary:The title compound, C16H19BrO4, is a derivative of osthol, isolated from the seeds of Imperatoria Osthruthium. The structure was solved in space group P, with two mol­ecules in the asymmetric unit, and was refined to a final R factor of 0.064. The two mol­ecules in the asymmetric unit differ in the orientation of their brominated substituent group. The benzo­pyran ring displays aromatic character. The packing of the mol­ecules in the lattice is mainly due to C—H⋯O hydrogen bonds.
