1,3-Bis(2-ethoxyphenyl)triazene methanol 0.33-solvate

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 center dot 0.33CH(3)OH. Two molecules related by a non-crystallographic pseudo-twofold rotation axis are linked via distinct intermolecular N-H center dot center dot center dot N hydrogen bonds, leading to the formation of a dimer with an R-2(2)(8) graph set. The third molecule is connected to the methanol molecule by O-H center dot center dot center dot N and N-H center dot center dot center dot O hydrogen bonds. There are a number of weak C-H center dot center dot center dot pi interactions, with H center dot center dot center dot pi distances ranging from 2.74 to 2.89 angstrom between the C-H groups and the aromatic benzene rings.
