title: 1,3-Bis(2-ethoxy-phen-yl)triazene methanol 0.33-solvate.
abstract: There are three independent mol-ecules of 1,3-bis-(2-ethoxy-phen-yl)triazene and a mol-ecule of methanol in the asymmetric unit of the title compound, C(16)H(19)N(3)O(2)·0.33CH(3)OH. Two mol-ecules related by a non-crystallographic pseudo-twofold rotation axis are linked via distinct inter-molecular N-H⋯N hydrogen bonds, leading to the formation of a dimer with an R(2) (2)(8) graph set. The third mol-ecule is connected to the methanol mol-ecule by O-H⋯N and N-H⋯O hydrogen bonds. There are a number of weak C-H⋯π inter-actions, with H⋯π distances ranging from 2.74 to 2.89 Å between the C-H groups and the aromatic benzene rings.
