3-[(E)-2-(5,7-Dichloro-8-hydroxy­quinolin-2-yl)vin­yl]-4-hydroxy­phenyl acetate

The two symmetry independent mol­ecules of the title compound, C(19)H(13)Cl(2)NO(4), show similar conformations with the acetyl group twisted strongly relative to the remaining, virtually flat (r.m.s. deviations = 0.0173 and 0.0065 Å), part of the mol­ecule. The hydroxyl groups of the 8-hydroxy­quin...

Sumario:The two symmetry independent mol­ecules of the title compound, C(19)H(13)Cl(2)NO(4), show similar conformations with the acetyl group twisted strongly relative to the remaining, virtually flat (r.m.s. deviations = 0.0173 and 0.0065 Å), part of the mol­ecule. The hydroxyl groups of the 8-hydroxy­quinoline residues are involved in intra­molecular O—H⋯N hydrogen bonds, which, in one case, forms a part of a three-center inter­action. Inter­molecular O—H⋯O hydrogen bonds assemble the mol­ecules into a one-dimensional polymeric structure extended along the a axis. The 4-hydroxy­phenyl group of one mol­ecule forms an O—H⋯O hydrogen bond, in which the hydroxyl H atom is disordered, with its inversion center counterpart.
