title: N'-(2-Hy-droxy-4-meth-oxy-benzyl-idene)-4-methyl-benzohydrazide.
abstract: The asymmetric unit of the title compound, C(16)H(16)N(2)O(3), contains four independent mol-ecules with different conformations; the dihedral angles between the two benzene rings in the mol-ecules are 39.7 (3), 45.4 (3), 50.6 (3) and 51.6 (3)°. Intramolecular O-H⋯N hydrogen bonds are observed in the molecule. In the crystal, N-H⋯O hydrogen bonds link the mol-ecules into two crystallographically independent chains propagating in [010], and each chain is formed by two alternating independent mol-ecules. Weak C-H⋯O inter-actions also occur.
