In the title compound, C(20)H(22)O(5)S, the dihedral angle between the mean planes through the thio-phene and benzene rings is 75.2 (1)°. The meth-oxy group is essentially coplanar with the benzene ring, the largest deviation from the mean plane being 0.019 (2) Å for the O atom. The malonate group assumes an extended conformation.

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 ox...
