Dimethyl 1-(3-hy-droxy-2-iodo-1-phenyl-prop-yl)-1H-1,2,3-triazole-4,5-dicarboxyl-ate.

In the title compound, C(15)H(16)IN(3)O(5), 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 meth-oxy-carbonyl 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 R(2) (2)(18) loops. The dimers are linked by C-H⋯O and C-H⋯N inter-actions into sheets lying parallel to the ac plane.
