Crystal structure of 1-(1-methyl-1H-imidazol-2-yl)-4-phenyl-1H-1,2,3-triazole dihydrate

The title compound, C(12)H(11)N(5)·2H(2)O, which crystallizes as a dihydrate, was obtained by Cu(I)-catalysed azide–alkyne cyclo­addition from 2-azido-1-methyl­imidazole and phenyl­ethyne. The dihedral angles between the central triazole ring (r.m.s. deviation = 0.004 Å) and the pendant imidazole (r.m.s. deviation = 0.006 Å) and phenyl rings are 12.3 (2) and 2.54 (19)°, respectively. In the crystal, the water mol­ecules are connected into [010] chains by O—H⋯O hydrogen bonds, while O—H⋯N hydrogen bonds connect the water mol­ecules to the organic mol­ecules, generating corrugated (100) sheets.
