Crystal Structure of 4,5-bis-(3,4,5-trimethoxyphenyl)-2\u3cem\u3eH\u3c/em\u3e-1,2,3-triazole methanol monosolvate

Abstract

The title compound, C20H23N3O6·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)°, while that between the 3,4,5-tri­meth­oxy­phenyl rings is 51.87 (5)°. In the crystal, the mol­ecules, along with two methanol solvent mol­ecules are linked into an R 4 4(10) centrosymmetric dimer by N—H⋯O and O—H⋯N hydrogen bonds
