5,5'-Bis(diethyl-amino)-2,2'-[butane-1,4-diyldioxy-bis(nitrilo-methyl-idyne)]-diphenol.

ABSTRACT: 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.
