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.

A mixture of 3-azido-2-iodo-3-phenylpropan-1-ol (0.3 g, 0.99 mmol) and dimethyl but-2-ynedioate (0.14 g, 0.99 mmol) was heated to reflux in toluene for 3 h. The solvent was evaporated under reduced pressure to afford the crude reaction mass which was then subjected to
using silica gel (60–120 mesh) as the and petroleum ether:ethyl acetate (80:20) as the mobile phase to give colourless blocks of (I) by slow recrystallization from the eluant. Yield: 0.35 g (81%); M.p.: 129–130 °C.Atom H1O5 was located from difference fourier map and refined freely [O—H = 0.74 (2) Å]. The remaining H atoms were positioned geometrically [C—H = 0.93 0.96, 0.97 and 0.98 Å] and refined using a riding model with Uiso(H) = 1.2 or 1.5 Ueq(C). A rotating group model was applied to the methyl groups. Sixteen outliers (5 - 1 4), (-4 1 6), (-4 2 5), (-4 3 4), (-2 3 0), (-4 1 0), (-4 4 4), (-2 - 1 3), (2 1 2), (-2 2 2), (-1 4 0), (-4 - 2 5), (5 0 4), (3 - 1 3), (-3 1 1) and (2 - 4 3) were omitted.

Experimental. The crystal was placed in the cold stream of an Oxford Cryosystems Cobra open-flow nitrogen cryostat (Cosier & Glazer, 1986) operating at 100.0 (1) K. |
Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

1,2,3-Triazoles are important in a wide range of industrial applications such as agrochemicals, corrosion inhibitors, dyes, optical brighteners as well as biologically active agents (Wamhoff et al., 1984). As part of our sudies in this area, we now describe the synthesis and structure of the title compound, (I) (Fig. 1).
The central triazole ring (N1–N3/C10/C11) is essentially planar [r.m.s deviation = 0.0034 Å] and makes a dihedral angle of 70.14 (5)° with the terminal benzene ring (C1–C6). The mean planes of the two methyl carboxylate groups (O1/O2/C14/C15 with maximum deviation = 0.0199 (6) Å at atom C14 and O3/O4/C12/C13 with maximum deviation = 0.0060 (6) Å at atom C12) make dihedral angles of 22.52 (7) and 40.93 (4)°, respectively with the triazole ring.
In the crystal (Fig. 2), the molecules are linked by O5—H1O5···O3, C9—H9A···O1, C13—H13B···O3, C13—H13C···O5 and C15—H15C···N2 hydrogen bonds (Table 1) into sheets parallel to ac plane.
