The crystal packing of the title compound, viewed along the a axis, showing the helical chain structures running along the b-axis direction. Yellow lines indicate the intermolecular O—H⋯O hydrogen bonds. Black dashed lines indicate weak intermolecular C—H⋯Cl interactions. Only H atoms involved in the hydrogen bonds are shown for clarity.
