(E,E)-1,2-Bis(2,4,5-trimeth­oxy­benzyl­idene)hydrazine

The asymmetric unit of the title compound, C(20)H(24)N(2)O(6), contains one half-mol­ecule, the complete mol­ecule being generated by a crystallographic inversion centre. The mol­ecule is nearly planar with a dihedral angle between the two benzene rings of 0.03 (4)° and the central C/N/N/C plane making a dihedral angle of 8.59 (7)° with each of its two adjacent benzene rings. The two meth­oxy groups at the ortho and meta positions are slightly twisted [C—O—C—C torsion angles = 7.23 (12) and 5.73 (13)°], whereas the meth­oxy group at the para position is almost coplanar with the attached benzene ring [C—O—C—C torsion angle = −2.02 (13)°]. The crystal structure is stabilized by a weak C—H⋯π inter­action.
