In the title compound, C15H16IN3O5, the central triazole ring is essentially planar (r.m.s deviation = 0.0034 Å) and makes a dihedral angle of 70.14 (5)° with the pendant benzene ring. The mean planes of the two methoxycarbonyl groups make dihedral angles of 22.52 (7) and 40.93 (4)° with the triazole ring. In the crystal, inversion dimers linked by pairs of O—H⋯O hydrogen bonds generate R22(18) loops. The dimers are linked by C—H⋯O and C—H⋯N interactions into sheets lying parallel to the ac plane.
