Abstract: There are three independent molecules of 1,3-bis(2-ethoxyphenyl)triazene and a molecule of methanol in the asymmetric unit of the title compound, C₁₆H₁₉N₃O₂·0.33CH₃OH. Two molecules related by a non-crystallographic pseudo-twofold rotation axis are linked via distinct intermolecular N-HN hydrogen bonds, leading to the formation of a dimer with an R₂²(8) graph set. The third molecule is connected to the methanol molecule by O-HN and N-HO hydrogen bonds. There are a number of weak C-H interactions, with H distances ranging from 2.74 to 2.89 Å between the C-H groups and the aromatic benzene rings.
