R factor = 0.060; wR factor = 0.204; data-to-parameter ratio = 16.0. 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—H hydrogen bonds, leading to the formation of a dimer with an R2 2 (8) graph set. The third molecule is connected to the methanol molecule by O—H N and N—H O hydrogen bonds. There are a number of weak C—H interactions, with H distances ranging from 2.74 to 2.89 A ˚ between the C—H groups and the aromatic benzene rings.
