摘要：

A new polymorph of 2-(benzotriazol-2-yl) acetic acid, C8H7N3O2, crystallizes in the space group C2/c (Z = 8). The non-planar molecule has a synplanar conformation of the carboxy group. The crystal structure features helices parallel to the b axis sustained by O-H center dot center dot center dot N hydrogen bonding which are similar to those in the known polymorph [Giordano & Zagari (1978). J. Chem. Soc. Perkin Trans. 2, pp. 312-315]. However, in the title structure, columns are formed by pi-pi stacking interactions between benzotriazole fragments of centrosymmetrically related adjacent molecules [centroidcentroid distances = 3.593 (10) and 3.381 (10) angstrom] whereas pi-pi stacking interactions are not observed in the other polymorph. In the crystal of the title compound, C-H center dot center dot center dot O interactions are also observed.
