Bottom Line: A U-shaped conformation is found in the title compound, C(19)H(21)N(3)O(5), with the benzene rings lying to the same side of the mol-ecule; the dihedral angle between them is 10.83 (16)°.An intra-molecular N(cb)-H⋯O(hy) (cb = carbmate and hy = hydr-oxy) hydrogen bond occurs, generating an S(6) loop.In the crystal, inter-molecular O(h)-H⋯O(ca) (ca = carbon-yl) and N(hz)-H⋯O(ca) (hz = hydrazine) hydrogen bonds lead to the formation of a supra-molecular chain, two mol-ecules thick, which propagates along the a axis; these are connected by C-H⋯O(ca) contacts.

ABSTRACT
A U-shaped conformation is found in the title compound, C(19)H(21)N(3)O(5), with the benzene rings lying to the same side of the mol-ecule; 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 intra-molecular N(cb)-H⋯O(hy) (cb = carbmate and hy = hydr-oxy) hydrogen bond occurs, generating an S(6) loop. In the crystal, inter-molecular O(h)-H⋯O(ca) (ca = carbon-yl) and N(hz)-H⋯O(ca) (hz = hydrazine) hydrogen bonds lead to the formation of a supra-molecular chain, two mol-ecules thick, which propagates along the a axis; these are connected by C-H⋯O(ca) contacts.
