چکیده
The title complex, C(26)H(38)N(4)O(4), was synthesized by the reaction of 4-diethyl-amino-2-hydroxy-benzaldehyde with 1,4-bis-(amino-oxy)butane in ethanol. It crystallizes as discrete centrosymmetric molecules adopting an extended conformation where the two salicylaldoxime groups are separated from each other. Intra-molecular O-H⋯N hydrogen bonding is observed between the hydr-oxy groups and oxime N atoms. Inter-molecular π-π stacking inter-actions [3.979 (2) Å] between aromatic rings are apparent in the crystal structure. Each ethyl group is disordered over two positions; in one the site occupancy factors are 0.55 and 0.45, in the other 0.53 and 0.47.

The title Schiff base bis-oxime compound, C(20)H(24)N(2)O(6), lies across an inversion centre and adopts an E configuration with respect to the C=N bond. In the mol-ecule, the oxime group is roughly coplanar with the benzene ring, forming a dihedral angle of 1.77 (2)°. An intra-molecular O-H⋯N hydrogen bond forms a six-membered ring with an S(6) motif. Weak inter-molecular C-H⋯O hydrogen bondin...

The asymmetric unit of the title Schiff base compound, C(30)H(38)N(4)O(2), comprises two crystallographically independent mol-ecules, A and B. The structure is non-merohedrally twinned with a refined BASF ratio of 0.219 (6):0.701 (6). Mol-ecule B shows both phenol-imine and keto-amine tautomeric forms in a single structure. The dihedral angles between the central ring and the two outer rings ar...

The asymmetric unit of the title compound, C(27)H(40)N(4)O(2), comprises one mol-ecule of a potentially tetra-dentate Schiff base ligand. The dihedral angle between the two phenyl rings is 67.13 (10)°. Strong intra-molecular O-H⋯N hydrogen bonds generate S(6) ring motifs. One terminal methyl among the four diethyl-amino groups is disordered over two positions with the refined site occupancy rat...

The mol-ecule of the centrosymmetric title compound, C(18)H(20)N(2)O(6), assumes an E configuration with respect to the azomethine C=N bond. The imino group is coplanar with the aromatic ring. Intra-molecular O-H⋯O and O-H⋯N bonds are found between the hydroxyl groups and adjacent O (or N) atoms. In the crystal structure, inter-molecular O-H⋯O bonds link each mol-ecule to two others, forming a ...
