چکیده
The formula unit of the title mol-ecular complex, 2C(16)H(16)N(2)O(3)·C(16)H(16)N(2)O(2), consists of two (E)-N'-[1-(2-hy-droxy-phen-yl)ethyl-idene]-2-phen-oxy-acetohydrazide mol-ecules and one mol-ecule of 2,2'-(1,1'-azinodiethyl-idyne)diphenol, with the latter located on a crystallographic inversion center. The acetohydrazide mol-ecules are linked into a supermolecular chain along the c axis by inter-molecular N-H⋯O hydrogen bonds. There are also intra-molecular O-H⋯N hydrogen bonds in both the acetohydrazide and diphenol mol-ecules.

In the title mol-ecule, C(16)H(16)N(2)O(2), the C-N bond lengths are 1.295 (5) and 1.300 (5) Å, which suggests that they are double bonds. The structure is stabilized by intra-molecular O-H⋯N and C-H⋯N, and inter-molecular C-H⋯O hydrogen-bond inter-actions.

The title Schiff base, C(21)H(26)N(2)O(2), contains two intra-molecular O-H⋯N hydrogen bonds between the hydroxyl groups and the nearest imine N atoms, each leading to a six-membered ring. Weak C-H⋯O hydrogen bonds result in a ladder network running along the a axis. In addition, inter-molecular C-H⋯π inter-actions serve to stabilize the extended structure.

The asymmetric unit of the title compound, C(16)H(16)N(2)O(2)·2H(2)O, contains one half-mol-ecule of diphenol and one water mol-ecule. The complete diphenol mol-ecule is generated by a crystallographic inversion centre. In the mol-ecule, the central C(meth-yl)-C=N-N=C-C(meth-yl) plane makes a dihedral angle of 8.88 (6)° with its adjacent benzene ring. In the crystal, the components are linked b...

There are two independent mol-ecules in the asymmetric unit of the title compound, C(16)H(16)N(2)O(3), in which the dihedral angles between the two aromatic rings are 13.0 (3) and 6.4 (3)°. Intra-molecular O-H⋯N and N-H⋯O hydrogen bonds are observed in both mol-ecules, forming S(6) rings in all cases.
