N-[(E)-4-Pyridylmethylene]-4-[(E)-4-(4-pyridylmethyleneamino)benzyl]aniline tetrahydrate
The title compound, C(25)H(20)N(4)·4H(2)O, crystallizes with the organic mol-ecule lying on a twofold rotation axis through the methyl-ene bridge C atom; there are also two water molecules in the asymmetric unit. The crystal structure is stabilized by C-H⋯O, O-H⋯O and O-H⋯N hydrogen bonds, linking the water mol-ecules to each other and to the pyridine N atom.

The benzohydrazide mol-ecule of the title compound, C(16)H(16)N(2)O(3)·2H(2)O, exists in a trans conformation with respect to the C=N double bond. The central O=C-NH-N=C plane [r.m.s. deviation of 0.0165 (1) Å for the five non-H atoms] makes dihedral angles of 6.04 (8) and 2.38 (8)°, respectively, with the hy-droxy- and eth-oxy-substituted benzene rings. The dihedral angle between these benzene...
