2-[(2-Meth-oxy-benzyl-idene)amino]-phenol.

ABSTRACT: In the title compound, C(14)H(13)NO(2), the azomethine double bond adopts an E conformation and the benzene rings form a dihedral angle of 77.70?(7)°. In the crystal, mol-ecules are linked by O-H?N and C-H?O hydrogen bonds and arranged in a zigzag fashion, forming infinite chains parallel to the c axis, resulting in a graph-set R(2) (2)(9) motif.

Project description:There are two independent mol-ecules in the asymmetric unit of the title compound, C16H17NO4, with similar conformations but some differences in their bond angles. Each mol-ecule adopts a trans configuration with respect to the methyl-idene C=N bond and is twisted with a dihedral angle between the two substituted benzene rings of 80.52 (7)° in one mol-ecule and 83.53 (7)° in the other. All meth-oxy groups are approximately coplanar with the attached benzene rings, with Cmeth-yl-O-C-C torsion angles ranging from -6.7 (2) to 5.07 (19)°. In the crystal, independent mol-ecules are linked together by O-H⋯N and O-H⋯O hydrogen bonds and a π-π inter-action [centroid-centroid distance of 3.6030 (9) Å], forming a dimer. The dimers are further linked by weak C-H⋯O inter-actions and another π-π inter-action [centroid-centroid distance of 3.9452 (9) Å] into layers lying parallel to the ab plane.

2-{[2-(2-Hy-droxy-3-meth-oxy-benzyl-idene)hydrazin-1-yl-idene]meth-yl}-6-meth-oxy-phenol.

Project description:The title compound, C(16)H(16)N(2)O(4), was obtained from the reaction of hydrazine hydrate and o-vanilin in absolute ethanol. The mol-ecule is almost planar (except for the methyl H atoms), with a mean deviation from the plane of 0.0259?Å. The mol-ecular structure also exhibits an approximate non-crystallographic twofold axis. Intra-molecular O-H?N hydrogen bonds occur. In the crystal, inter-molecular C-H?O hydrogen bonds generate mol-ecular zigzag sheets. The sheets stack through C-H?? inter-actions, leading to a three-dimensional-network.
