چکیده
In the title compound, C(19)H(19)NO(4), the dihedral angle between the mean planes through the benzene rings is 82.18 (7)°. The C=N double bond is trans-configured. The mol-ecules are linked into centrosymmetric dimers via pairs of O-H⋯N hydrogen bonds with the motif R(2) (2)(6). The crystal packing also features C-H⋯O inter-actions. The methyl group attached to one of the aromatic rings is disordered over two almost equally occupied positions [occpancy ratio = 0.51 (4):0.49 (4)].

The title compounds, C19H16ClNO5, (I), and C19H15Cl2NO5, (II), both crystallize in the monoclinic space group P21/n. They differ essentially in the orientation of the methyl acetate group, with the C=O bond directed towards the NO2 group in (I) but away from it in (II). In compound (I), the mean plane of the methyl acrylate unit is planar, with a maximum deviation of 0.0044 (2) Å for the methyl...

In the title compound, C(18)H(17)NO(4), the hy-droxy-ethanimine group is essentially coplanar with the ring to which it is attached [C-C-N-O torsion angle = 179.94 (14)°]. The mol-ecules are linked into cyclic centrosymmetric R(2) (2)(6) dimers via O-H⋯N hydrogen bonds and the crystal packing is further stabilized by C-H⋯O inter-actions.
