4-(4-Hy­droxy­methyl-1H-1,2,3-triazol-1-yl)benzoic acid

In the title compound, C(10)H(9)N(3)O(3), there is a small twist between the benzene and triazole rings [dihedral angle = 6.32 (7)°]; the carb­oxy­lic acid residue is almost coplanar with the benzene ring to which it is attached [O—C—C—C torsion angle = 1.49 (19)°]. The main deviation from coplanarity of the non-H atoms is found for the hy­droxy group which is almost perpendicular to the remaining atoms [N—C—C—O torsion angle = −75.46 (16)°]. In the crystal, the presence of O—H⋯O (between carboxyl groups) and O—H⋯N (between the hy­droxy group and the triazole ring) hydrogen bonds leads to supra­molecular chains along [03[Image: see text]]. The chains are connected into sheets via C—H⋯O(hy­droxy) inter­actions.
