title: N,N'-Bis(3,4-dimethoxy-benzyl-idene)butane-1,4-diamine.
abstract: 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.
