چکیده
In the title Schiff base, C(29)H(26)N(2)O(4), the complete molecule is generated by a crystallographic twofold axis and is V-shaped. The planes of the benzene rings of the central diphenyl-methane unit make a dihedral angle of 78.11 (4)° while adjacent benzene and 5-meth-oxy-salicyl-idene rings are twisted with respect to each other by a dihedral angle of 11.84 (8)°. The Schiff base is in the enol-imino form and an intra-molecular O-H⋯N hydrogen bond is observed.

The asymmetric unit of the title compound, C(18)H(20)N(2)O(4), contains one-half mol-ecule with an inversion center located at the centroid of the mol-ecule. In the crystal, mol-ecules are linked by C-H⋯π inter-actions, forming layers parallel to (101). An intra-molecular O-H⋯N hydrogen bond also occurs.

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...

The complete mol-ecule of the title compound, C(42)H(36)N(6)O(2), is generated by a crystallographic twofold axis with two C atoms of the central phenyl group lying on the axis. In the independent part of the mol-ecule, one amino group is involved in an intra-molecular N-H⋯O hydrogen bond, and the two adjacent phenyl rings are twisted from the plane of the pyrazolone ring with dihedral angles o...

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)°.
