چکیده
In the title compound, C(18)H(16)ClNO(4), the dihedral angle between the mean planes through the aromatic rings is 83.8 (8)°. The hy-droxy-ethanimine group is essentially coplanar with the ring to which it is attached [O-N-C-C torsion angle = -177.96 (13)°]. The mol-ecules are linked into centrosymmetric R(2) (2)(6) dimers via O-H⋯N hydrogen bonds. The crystal packing is further stabilized by C-H⋯O inter-actions.
