The title compound, C(21)H(17)ClO(3), which crystallizes as one of two possible oxo/hy­droxy-fulvene prototropic tautomers, possesses a strong intra­molecular O—H⋯O hydrogen bond that closes a seven-membered ring. The dihedral angles between the central five-membered ring and two pendant rings are 5...

description The title compound, C(21)H(17)ClO(3), which crystallizes as one of two possible oxo/hy­droxy-fulvene prototropic tautomers, possesses a strong intra­molecular O—H⋯O hydrogen bond that closes a seven-membered ring. The dihedral angles between the central five-membered ring and two pendant rings are 55.05 (9) and 44.51 (10)°. The crystal packing is characterized by weak inter­molecular C—H⋯O inter­actions between an H atom of the oxymethyl­ene unit and the carbonyl group of an adjacent mol­ecule, resulting in formation of chains of mol­ecules along the a axis.
