The asymmetric unit of the title compound, C(17)H(19)N(3)O(3)·CH(4)O, comprises two Schiff base mol-ecules and two methanol solvent mol-ecules. The Schiff base mol-ecules are approximately planar, with r.m.s. deviations from the planes defined by the non-H atoms of 0.107 and 0.154 Å, and with dihedral angles between the benzene rings of 4.49 (15) and 8.39 (15)°, respectively. This near-planarit...

In the title compound, C(15)H(13)N(3)O(4)·CH(3)OH, the dihedral angle between the two substituted benzene rings is 66.7 (2)°. An intra-molecular O-H⋯N hydrogen bond is observed in the Schiff base mol-ecule. In the crystal structure, the Schiff base and solvent mol-ecules are linked into chains running along the a axis by inter-molecular O-H⋯O and N-H⋯O hydrogen bonds.

In the title compound, C(17)H(15)N(3)O(2)·C(2)H(6)O, Schiff base molecules are linked by a hydr-oxy-amido hydrogen bond into a helical chain running along the b axis. This chain is consolidated by two other hydrogen bonds; the ethanol solvent mol-ecule is a hydrogen-bond donor to the amide group and a hydrogen-bond acceptor for the indolyl NH group of an adjacent Schiff base mol-ecule.

The title compound, C(15)H(13)N(3)O(4)·CH(4)O, was synthesized from the reaction of 4-methoxy-benzaldehyde with 4-nitro-benzohydrazide in methanol. The benzene rings of the Schiff base mol-ecule are nearly coplanar, making a dihedral angle of 7.0 (3)°. The methanol solvent mol-ecules are linked to the Schiff base mol-ecules by N-H⋯O, O-H⋯N and O-H⋯O hydrogen bonds, forming chains running parall...

In the title compound, [Na(4)(C(15)H(9)N(4)O(4))(4)(CH(3)OH)(4)], the N(3)O(3) environment around the Na(+) ion is distorted octa-hedral. In the unit cell, four Na(+) ions are bridged by four Schiff base anions, leading to a tetra-nuclear complex with -4 symmetry. O-H⋯N hydrogen bonds between the methanol mol-ecule and the Schiff base anion stabilize the structural set-up.
