چکیده
In the title compound, C(20)H(19)O(4)P, the dihedral angle between the phenyl rings is 73.3 (4)° and the dihedral angles between the benzene ring and the two phenyl rings are 43.0 (3) and 54.3 (1)°. In the crystal, O-H⋯O hydrogen bonds and weak O-H⋯O inter-actions are observed, which form a supra-molecular sheet parallel to (010).

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-m...

Mol-ecules of the title compound, C(34)H(38)N(4)O(2), lie across crystallographic inversion centres. The crystal packing can be described by alternating zigzag chains along the c axis in which the molecules are linked by van der Waals interactions. There is an intra-molecular O-H⋯N hydrogen bond and the two benzene rings in the asymmetric unit make a dihedral angle of 79.81 (6)°.

Mol-ecules of the title compound, C(23)H(30)N(2)O(4), are located on a crystallographic mirror plane. The mol-ecule has a curved shape with the dihedral angle formed between the two benzene rings being 55.26 (5)°. Intra-molecular O-H⋯N hydrogen bonds are noted. In the crystal, supra-molecular layers are formed in the ac plane owing to the presence of C-H⋯π inter-actions.
