Crystal structure of 4,5-bis(3,4,5-trimethoxyphenyl)-2H-1,2,3-triazole methanol monosolvate

The title compound, C20H23N3O6 center dot CH3OH was synthesized by [3 + 2] cycloaddition of (Z)-2,3-bis(3,4,5-trimethoxyphenyl)-acrylonitrile with sodium azide and ammonium chloride in DMF/water. The central nitrogen of the triazole ring is protonated. The dihedral angles between the triazole ring and the 3,4,5-trimethoxyphenyl ring planes are 34.31 (4) and 45.03 (5)degrees, while that between the 3,4,5-trimethoxyphenyl rings is 51.87 (5)degrees. In the crystal, the molecules, along with two methanol solvent molecules are linked into an R-4(4)(10) centrosymmetric dimer by N-H center dot center dot center dot O and O-H center dot center dot center dot N hydrogen bonds.
