Crystal structure of methyl 2-[5-(2-hy­droxy­phen­yl)-2H-tetra­zol-2-yl]acetate

The title compound, C(10)H(10)N(4)O(3), was synthesized by the esterification of hy­droxy­phenyl tetra­zole. There is an intra­molecular O—H⋯N hydrogen bond present involving the hy­droxy group and the tetra­zole ring. The tetra­zole ring is inclined to the phenol ring by 2.85 (13)°, while the methyl acetate group is almost normal to the tetra­zole ring, making a dihedral angle of 82.61 (14)°. In the crystal, mol­ecules are linked by pairs of C—H⋯O hydrogen bonds, forming inversion dimers. Within the dimers, the phenol rings are linked by offset π–π inter­actions [inter­centroid distance = 3.759 (2) Å]. There are no further significant inter­molecular inter­actions present in the crystal. The hy­droxy group is disordered about positions 2 and 6 on the benzene ring, with a refined occupancy ratio of 0.531 (5):0.469 (5).
