چکیده
The asymmetric unit of the title compound, C(11)H(14)N(2)O(3), contains two independent mol-ecules with close conformations; the C=N-N-C torsion angle is 176.4 (1)° in both mol-ecules. In the crystal, inter-molecular N-H⋯O and C-H⋯O hydrogen bonds link the mol-ecules into chains running along the [01] direction.

The title Schiff base compound, C(22)H(28)N(2)O(4), was synthesized by the reaction of 3,4-dimethoxy-benzaldehyde and 1,4-diamino-butane in methanol. The mol-ecule is located on a center of inversion with one half-mol-ecule in the asymmetric unit. Both C=N double bonds are in a trans configuration. Inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into a three-dimensional network.
