(1E,2E)-1,2-Bis[1-(2-methoxyphenyl)ethylidene]hydrazine
There are two crystallographically independent molecules in the asymmetric unit of the title compound, C(18)H(20)N(2)O(2). 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...

Sumario: | There are two crystallographically independent molecules in the asymmetric unit of the title compound, C(18)H(20)N(2)O(2). 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 Å in one molecule, and 0.0163 and 0.0207 Å 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) Å] and C⋯O [3.3284 (16)–3.3863 (15) Å] short contacts. C—H⋯π interactions are also observed. |
