(1E,2E)-1,2-Bis[1-(2-methoxyphenyl)ethylidene]hydrazineThis paper is dedicated to the late His Majesty King Chulalongkorn (King Rama V) of Thailand for his numerous reforms to modernize the country on the occasion of Chulalongkorn Day (Piyamaharaj Day) which fell on the 23rd October.

There are two crystallographically independent molecules in the asymmetric unit of the title compound, C18H20N2O2. The two molecules exist in an E,E configuration with respect to the two C=N double bonds. The dihedral angles between the two benzene rings in each molecule are 16.89 (6) and 18.84 (6)°. In each molecule, the two methoxy groups are coplanar with their attached benzene rings, with r.m.s. deviations of 0.0078 and 0.0336 in one molecule, and 0.0163 and 0.0207 in the other. An intramolecular C—H...O hydrogen bond is present in one molecule. In the crystal structure, molecules are arranged into ribbons along the c axis. These ribbons are further stacked along the a axis. The molecules are consolidated by C...N [3.306 (2)–3.427 (2) ] and C...O [3.3284 (16)–3.3863 (15) ] short contacts. C—H...π interactions are also observed.
