title: 2,3-Dimeth-oxy-benzaldehyde azine.
abstract: There are one-and-a-half independent mol-ecules in the asymmetric unit of the title compound, C(18)H(20)N(2)O(4). One mol-ecule is centrosymmetric with the mid-point of the N-N bond located on a center of inversion. In the other, which lies on a general position, the benzene rings are aligned at 21.6 (1)°. Weak inter-molecular C-H⋯O hydrogen bonding is present in the crystal strcture.
