N′-(2-Hy­droxy-4-meth­oxy­benzyl­idene)-4-methyl­benzohydrazide

摘要

The asymmetric unit of the title compound, C16H16N2O3, contains four independent mol­ecules with different conformations; the dihedral angles between the two benzene rings in the mol­ecules 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 mol­ecules into two crystallographically independent chains propagating in [010], and each chain is formed by two alternating independent mol­ecules. Weak C—H⋯O inter­actions also occur.
