Abstract
A U-shaped conformation is found in the title compound, C19H21N3O5, with the benzene rings lying to the same side of the molecule; the dihedral angle between them is 10.83 (16)°. The dihedral angle formed between the hydrazinecarbonyl and carbamate residues is 68.42 (13)°. The carbonyl groups lie approximately at right angles to each other [O—C⋯C—O pseudo torsion angle of 107.7 (3)°], and the conformation about the C12=N3 bond [1.279 (4) Å] is E. An intramolecular Ncb—H⋯Ohy (cb = carbmate and hy = hydroxy) hydrogen bond occurs, generating an S(6) loop. In the crystal, intermolecular Oh—H⋯Oca (ca = carbonyl) and Nhz—H⋯Oca (hz = hydrazine) hydrogen bonds lead to the formation of a supramolecular chain, two molecules thick, which propagates along the a axis; these are connected by C—H⋯Oca contacts.
