N′-(3-Eth­oxy-2-hy­droxy­benzyl­idene)-2-hy­droxy-3-methyl­benzohydrazide

The title compound, C(17)H(18)N(2)O(4), crystallizes with two independent mol­ecules in the asymmetric unit. The two benzene rings in each mol­ecule make dihedral angles of 7.6 (3) and 3.9 (3)°. Intra­molecular O—H⋯N and O—H⋯O hydrogen bonds are present in each mol­ecule. In the crystal, N—H⋯O hydro...

Sumario:The title compound, C(17)H(18)N(2)O(4), crystallizes with two independent mol­ecules in the asymmetric unit. The two benzene rings in each mol­ecule make dihedral angles of 7.6 (3) and 3.9 (3)°. Intra­molecular O—H⋯N and O—H⋯O hydrogen bonds are present in each mol­ecule. In the crystal, N—H⋯O hydrogen bonds link the mol­ecules into chains propagating in [010]. The are also a number of C—H⋯O and π–π inter­actions present [centroid–centroid distances = 3.874 (4) and 3.904 (3) Å], that result in the formation of a three-dimensional network.
