O, the central benzene ring makes dihedral angles of 46.64 (10) and 49.34 (10)° with the two outer benzene rings, and the two outer benzene rings form an angle of 39.13 (8)°. There are two intramolecular O—H⋯N hydrogen bonds involving the two hydroxy groups, which generate
S
(6) ring motifs. In the crystal structure, the Schiff base molecules are linked into a chain along the
a
axis by C—H⋯π interactions. The acetone solvent molecules are attached to the chain
via
C—H⋯O hydrogen bonds.
